Q: WooCommerce: How to require State Dropdown box in ADMIN New Order section I am trying to require a handful of fields in the Admin area of WooCommerce inside of the Create New Order form. I have successfully worked out how to do this for all of the fields except for the State drop-down menus. Here is what I have so far (all of this code is functioning properly):
// Require certain fields in NEW ORDER creation via Admin
add_filter('woocommerce_admin_billing_fields', 'woocommerce_require_admin_billing_fields');
function woocommerce_require_admin_billing_fields( $fields ){
    $fields['first_name']['custom_attributes'] = array( 'required' => '1' );
    $fields['last_name']['custom_attributes'] = array( 'required' => '1' );
    $fields['address_1']['custom_attributes'] = array( 'required' => '1' );
    $fields['city']['custom_attributes'] = array( 'required' => '1' );
    $fields['postcode']['custom_attributes'] = array( 'required' => '1' );
    $fields['country']['custom_attributes'] = array( 'required' => '1' );
    $fields['email']['custom_attributes'] = array( 'required' => '1' );
    $fields['phone']['custom_attributes'] = array( 'required' => '1' );
    return $fields;
}
add_filter('woocommerce_admin_shipping_fields', 'woocommerce_require_admin_shipping_fields');
function woocommerce_require_admin_shipping_fields( $fields ){
    $fields['address_1']['custom_attributes'] = array( 'required' => '1' );
    $fields['city']['custom_attributes'] = array( 'required' => '1' );
    $fields['postcode']['custom_attributes'] = array( 'required' => '1' );
    $fields['country']['custom_attributes'] = array( 'required' => '1' );
    $fields['state']['custom_attributes'] = array( 'required' => '1' );
    return $fields;
}
// Require fields that are not included in woocommerce_admin loops
function vic_require_admin_fields() {
     echo '<script>document.getElementById("excerpt").setAttribute("required", "1")</script>';              // order notes (excerpt)
     echo '<script>document.getElementById("_payment_method").setAttribute("required", "1")</script>';      // payment method
 }
 add_action( 'woocommerce_admin_order_data_after_shipping_address', 'vic_require_admin_fields' );

I have tried to require the "State" drop-down field in a similar manner as the rest (through a filter targeting the "state" id) and I have also attempted to target it with a javascript action, but both efforts produced no solution. It looks like the way the form is constructed is through a boostrap drop-down? The actual  tag is set to display: none, so I can't really do much with that.
I can see that when I select a selection without a state, the SELECT field turns into an INPUT field, which is I think why I am unable to target it to add the required attribute:

It's alright if I can't do this with a filter. I'm thinking I may need some javascript attached to the button for form validation maybe? I couln't seem to find the actual form id, in order to validate through javascript, though I will probably look more around this evening when I'm home.
Any ideas to help me find a solution will be much appreciated!

Q: How do I set the properties of a DirectShow Filters Ok I have this 3d tv Transformation Filter. I can easily configure its properties by using GraphEdit, right click on its properties and set whatever I want.
Now I want to set the properties automatically  by building a Filter Graph in C++.
I've read up the Windows SDK documentation and find out that I have to use the IKsPropertySet function (correct me if i'm wrong).
I have to use IKsPropertySet::QuerySupported to check whether it support this kind of property or not. And to do that, i have to know  the
dwPropID
[in] Identifier of the property within the property set.
But how can I get that ID. Like this filter have the property of adjusting horizontal and vertical, but i cannot find the ID of that properties.
Is there anyway to list down all the properties ID that a filter support ?

A: Functionality for directshow filters are usually exposed through interfaces. Either standard directshow interfaces, or custom interfaces. You get the interface by calling QueryInterface on the COM object (probably your filter, but it could also be one of the pins). What kinds of interfaces the filter exposes is probably described in the filter documentation.
I think you shold try to take a look at some information about directshow and COM before you dive into coding. Here you'll find some info about DirecShow. And here you'll find some about COM.
If you are planning to do this in .net, try searching for directshownet. It's an open source project that wraps the directshow API for use in managed code.

Writers are, of necessity, sedentary creatures. The craft demands it. Authors report the effort to balance time spent at the computer screen or notebook and movement is inherent to the writing process.
Joanna Lloyd, a novelist in Cairns, is sedentary by another necessity. A Multiple Sclerosis (MS) sufferer, she writes to create and as an exercise in freedom from enforced inactivity. Her mind, her soul revels in the world of imagination. She comes to the page sans the appendage capability for movement taken for granted by the majority.
A New Guinean born Australian, Joanna has haunting memories of a childhood spent with missionary parents on Bellio Island, a volcanic emerald dot in the turquoise vastness of the Arafura Sea, north of Madang.
"As a child it was a long, long boat ride to anywhere, and I remember women put their babies in the meat safe to save them from snakes and flies," she relates.
Joanna is a perfect host to my inquiring interview. She punctuates all answers with (I learn quickly in our short time together), a trademark beatific smile.
The rebellion in response to this abrupt intervention remained latent until she wrote her first published novel, Beyond Innocence (2012) published by Crimson Romance.
"In the process of bringing my main character to the page, I realised I was expressing my frustrations, which were initiated by my relationship with and view of my mother, and in fact, I could hear my mother's when I got inside the character," she flashes that smile.
When she was diagnosed with MS, in 1986, her immediate response was to pack up her family, leave her mediation consultancy and travel around the world.
The sudden loss of her beloved husband, David, and the increasing debilitation caused by the disease, pushed her toward a writing career.
"I have always loved reading, so I will tell a rollicking good tale; one that is outside myself.
These days, inspiration comes while she is exercising in her pool surrounded by the tropical plants of her garden. She shows me the special chair that lowers her into the water, where she can move quite well aided by the liquid support. Her view is to the emerald clad mountains that are the rainforest backdrop to Cairns.
"I tell my carer to grab a pencil and pad; you never know what will come of the day's exercise." This time she laughs.
The words get to the page through a speech recognition program. It is a labourious process, as the software is often mistaken and corrections are made by way isolating the mistakes and repeating the corrections.
Joanna leads me into the office where she writes; the same view to the mountains from her window, now hosts a gathering of monsoonal thunderheads.
That smile is tinged with wistfulness this time. She claims she has come to terms with what is.
Sonja is a communication specialist and passionate author with a rich background in multi-media journalism, public relations and marketing. As well as her expressive professional life, Sonja teaches meditation in her Freshwater studio, in Cairns, Australia. Sonja has raised three children, who are her best friends. Life Balance = Meditation. Love. Communication.


San Marcos Councilmember Chris Jones (center) argues for the council to table an item setting council compensation. Listening in are San Marcos City Manager Rick Menchaca (left) and Councilmember Fred Terry (right). Photo by Sean Batura.
On the eve of an election that could define a new voting majority on the city council, San Marcos City Councilmembers voted Monday to table two contentious items regarding compensation.
Councilmembers tabled an employment agreement with the city's police officers, then tabled a second and deciding vote on payment for themselves.
Danny Arrendondo, president of the San Marcos Police Officers Association (SMPOA), said some of his membership wanted clarification regarding aspects of the proposed police agreement. The city and the SMPOA have been working on a three-year agreement during meet and confer negotiations.
Arredondo said 92 members of the San Marcos Police Department (SMPD) were at SMPOA's last meeting. All city police, whether they are members of the association, have a right to vote on the terms of the employment agreement. Arredondo said the only law enforcement officers who do not vote on police employment agreements are the department's two assistant chiefs and the chief. The chief's pay is negotiated separately from the meet and confer negotiations.
Arredondo said one goal of the meet and confer negotiations is to attract and retain high-quality employees.
In a related development, councilmembers voted, 6-1, to allot up to $45,000 more to the law firm Denton, Navarro, Rocha and Bernal (DNRB) for its work in negotiating for the city with the police and fire fighters associations. DNRB also is drafting the employment agreements with the SMPOA and the San Marcos Professional Fire Fighters Association (SMPFFA).
The city already has paid DNRB more than $70,000, which is the amount originally agreed upon. DNRB has represented the city in about 14 nine-hour rounds of meet and confer negotiations with each professional association. Additional meet and confer negotiations are scheduled between the city and SMPFFA.
"Spending $70,000 for an outside attorney, and now we're asking for another $45,000 — I think it should have been done for $70,000," said Councilmember John Thomaides, who voted against the additional funds.
Assistant City Manager Collette Jamison said the city may not have to spend all of the additional $45,000 once the contracts between and fire and police associations are finalized.
Councilmember Chris Jones asked whether the meet and confer process would have to be started from "square one" if the council chose not to retain DNRB. City Attorney Michael Cosentino replied that the meet and confer process could continue on without DNRB, but on pain of losing the relationships and knowledge DNRB has developed in its work up to this point.
As the council approached a second and final reading on ordinance that would pay themselves $500 per month and the mayor $750 per month, Jones motioned to table the item. Councilmembers Fred Terry and Pam Couch voted against tabling the council compensation item, and the tabling passed, 5-2.
After Jones outlined his reasoning, San Marcos Mayor Susan Narvaiz said the discussion regarding city councilmember pay began in February 2009.
Jones replied that he had been referring to the current debate on council compensation, not the discussion at the time of its inception.
The council voted, 4-3, for the compensation on first reading at its Oct. 22 meeting. Voting in favor of the compensation at that meeting were Councilmembers Couch, Jones, Terry and Gaylord Bose. Voting in opposition were Narvaiz, Thomaides and Councilmember Kim Porterfield.
Two seats are at stake in the city council election on Tuesday. Among sitting councilmembers, only Thomaides is running for re-election.
On June 16, councilmembers voted down the proposed stipends without discussing the matter in open session. Terry and Jones cast the only votes for the salaries at that meeting.
In November 2008, city voters gave 80.28 percent approval to a charter amendment "to provide that city council compensation shall be set in a public forum by ordinance of the city council," in the language of the ballot.
After the Monday city council meeting, Couch said she hopes the council compensation item will be placed on next meeting's agenda.
The pay discussion actually started back in the '80's, but like many a political hobby-horse, it continues to circle the show ring, each time with a new rider and an altered rationale. Think Sign Ordinance, Downtown Bar Ordinance, Residential Zoning Ordinance, Noise Ordinance–even the ancient discussion of whether our public safety personnel wanted the security of Civil Service, with its built-in inequities, or the riskier Employment by Contract–maybe fairer, but not so secure.
Whew! Next thing we know, the Wonder World cut to RR12 and Loop 110 will be brand new concepts instead of two-decade battles with UPAC and the State and others. So far, five environmental studies–esp. for endangered birds–and hardly a decision made except that both are necessary for SM not to choke on its own traffic. Not a bird found yet, to my knowledge. Same with CBD parking.
Hint: If it is critical for some reason that it be done, and if it is feasible, and if it won't lead off a cliff, do it. If it doesn't meet the critical needs test or the smell test, etc., don't do it. Flirting is a waste of talent.
Maybe Pam was making a joke at her last meeting — "clear message." Your average voter who turned out for the Presidential election probably couldn't tell you if coucil was paid or volunteer. When they read that compensation should be set in "public" and by "ordinance of .. council," I am sure that sounded preferable to in secret or by whim of the Mayor. Clear language would have noted that council was moving from volunteer to paid with tax dollars and would have made clear that Council itself would determine its compensation. That would have been clear, but it might not have passed.
Yep! Mr. McGlothlin, you nailed it quite accurately there.
It's amazing what our City Council majority can convince themselves of.
I think I voted for it in 2008 knowing what it meant, alhtough I'm not sure if I would still vote for it now. When you start second-guessing voters based on hunches and what you think they were thinking, it becomes a slippery slope.
Vague proposition language leaves people to argue over what was approved. Second-guessing is different — what voters approved was clear but you think they are wrong. I agree that second-guessing is a slippery slope or downright undemocratic.

Minutes after the aircraft hit the second World Trade Center tower, President George W. Bush was on national (and international television) talking about the incident. Besides the President, many senior US administration officials have been on TV on a regular basis to update everyone on what has been happening. This helps prevent rumours and speculation, and more importantly, gives confidence to the people watching that there is someone in charge and rallies them towards a common cause.
If there is one thing that comes out watching the aftermath of the attacks in the US, it is that of the need for immediate, clear and extensive communications. This is one area which India has been lacking in.
India has had two serious "foreign affairs" crises in the past few years: the hijacking of IC-184 to ironically, Kandahar in Afghanistan, and the Kargil War. Most recently, we had the India-Pakistan summit in Agra, which was very much in the full glare of the media. In every case, we had a public relations and communications disaster.
Governments screw up all the time and democracies are most imperfect. But the Americans have now shown you how a government of real systems, laws and experience gets its act together. Unlike us during Agra, Kandahar, Kargil, this one is not hiding from the media. Nor is it speaking selectively to certain journalists or channels, answering a few questions, and hoping the rest of the media would pick it up.
Another learning from the events of the past week has been the bipartisanship among the Republicans and the Democrats in the US. The Congress and Senate met and approved not just aid of USD 40 billion towards the rebuilding effort, but also the use of military force. There was not a single dissenting voice. The whole nation, led by its leaders, has rallied about the President. This is the political maturity that Indian leaders need to learn.
Contrast the trademark shrillness of our public response with the understated dignity of the Americans. There is no public outcry to go bomb somebody – here, both during Kargil and Kandahar, public opinion was like a lynch mob, cross the LoC, carpet bomb something, sort this problem out "once and forever".In the US, no one of any consequence has said a word against Islam or the Arabs, there is no clamour for instant revenge.
As we watch TV and the images unfold in front of us, it is time to do some thinking about what we as a nation can learn from America. Crises and disasters are not under our control. How we respond is.


Paul paints a picture of the followers of Christ as early risers who get dressed in the dark. The resurrection of Jesus Christ was a defining moment in human history. The next one will be His return. We are living in the dark just before the dawn. This is the time when we should be living as if we are preparing for the next life, a new day. In this sermon, learn how the second coming of Jesus Christ serves as motivation for holy living in this present age.

Q: How to go to a specific line number in gedit, using guake? I use guake which let me directly open a file if I ctrl+click on it.
I have the need to open a file AND directly go to the specific line shown on screen.
How can I set guake to make it work?
I tried writing this
gedit %(file_path):s%(line_number)s

in guake settings, but that doesn't work.
Can you help me, please?

A: If you have a look at man gedit, it says the syntax is this:
gedit [OPTION...] [FILE...] [+LINE[:COLUMN]]

I don't know how exactly your Guake settings need to be formatted (I'm especially confused by the two "s"), but the command which gets finally run should look like this to e.g. open FILE at line 42:
gedit /PATH/TO/FILE +42

A: Gedit uses Vim/less-like line number support. See man gedit:
gedit [OPTION...] [FILE...] [+LINE[:COLUMN]]

So, you probably need:
gedit %(file_path)s +%(line_number)s

(Not sure what the s is, I'm not familiar with guake config, so I retained it.)

This Feeling Big in 2019: BUTE
Of the vast list of artists This Feeling chose to be in their Big in 2019 list, one I hadn't come across prior to the names being announced, was Welsh indie band BUTE. Hailing from Cardiff, the four piece are a band that seemingly have a range of influences from the heavier side of indie-rock (think Foals/The Strokes) and when I first listened to new single Rest Assured, I honestly couldn't recall being as excited in some time about an upcoming band. We spoke to to Luke (Lead guitar) and John (Drums) ahead of the release and have reviewed the track in true H2N style.
It's easy to see within seconds of listening to Rest Assured, why BUTE secured top support slots with the likes of The Blinders and Sheafs in 2018. Rest Assured has an overarching style that both fits the heavy-indie genre like a glove in the same way these bands have, but is so distinct and ambitious that it has set BUTE aside from the rest, very early in their career. The biggest compliment I can pay at this early stage is that BUTE sound like a band that have been making music for years
Their musical structure is well formed and the raucous sounds balance harmoniously to create a strong, quite superb sophomore single. At 3:31 you might expect two solid verses and choruses with a bridge but this track really builds as it goes in unorthodox fashion. The opening guitars crashing into heavy drums before slowing right down into a 90 second escalation to an explosion of noise that is both rousing but well balanced. The song is only ten days old but I'm addicted, it's a formula that has worked well for the guys and blends all it means to be an indie band with a few quirky notes to give it a BUTE twist.
I imagine the next few singles from these guys will be quite safe; the driving drum track on Rest Assured is a real asset I can see them recycling, whilst the crescendo to the Kasabian-esque drop is a delight they will likely want to use again. For many this would be a criticism but I would be more than happy to listen to two or three versions of this track with new lyrics and a new melody. Being so young though, they may go on to prove me completely wrong and experiment with their honed sound – another idea I would be all for experiencing in 2019.
There is genuine excitement at H2NHQ with this band – unlike many on the list which will be "Big in 2019", I think 2019 will be a year of discovery for BUTE. They'll find their real, true sound and they will actually blow up in around another 18 months time when the fan base is built and their tracks perfected. I can see BUTE lasting a long time and look forward to sharing the ride with them!

How does it feel to be named one of This Feeling's Big in 2019?
Luke: Feel very privileged.
Jon: Honoured to be included on such a strong list of bands.
What's your relationship been like so far with This Feeling?
Jon: Amazing, most of what we did last year would not have been possible without their support
If you had to say one, what was the band highlight of 2018?
Luke: UK/ Paris Tour
Jon: Specifically Glasgow and our weekend in Scotland to end the tour
You had some great airplay on the last single, you must feel like something big is about to happen for BUTE?
Luke: We take each day and opportunity as it comes we love what we do and are always eager to progress the band further. Hopefully 2019 will be bigger again.
Your new single Rest Assured is out very soon – what's the track about?
Luke: Urmmm… I guess the actual song is about frustration? Being stuck in the same place or situation and being frustrated by it. The song for me is good for letting your frustrations out it's loud, pumpy and funky.
How excited are you to get this one out?
Jon: Buzzing, it's been a long time coming. Our first single was recorded such a long time ago and I feel that we've changed a lot as a band since then.
And what are your plans for the rest of the year, can we expect new music and touring?
Luke: Definitely new music we have lots planned to release throughout 2019. Same with a tour we have been discussing this for a few months and hope to have some announcements soon.
Jon: More music than we put out last year, that's for sure
There seems to be a lot of new artists coming out of Wales currently, why do you think this resurgence is happening now?
Luke: I feel there is a lot more support for up and coming artists throughout Wales these days. This feeling has played a big part in this.
Who/what made you want to get into making music?
Luke: To speak for myself it's something I have always wanted to do and never thought of doing anything different.
Jon: Society man. Nah, to be honest it's the only thing I'm quite good at
Where did you all meet and what does the name BUTE signify?
Jon: The name BUTE is a tribute to Cardiff, the City we all met and grew up in. The Bute family has strong ties to Cardiff, and had a large role to play in the development of the City through building the docks and refurbishing the Castle. The word Bute actually originates from the Isle of Bute in Scotland. Sam our Bassist was born in Glasgow, so there's also a Scottish connection there.
By January 2020, what would you like to have achieved?
Luke: Festivals. Music video. 14 date+ tour.
Jon: To have conquered the Cardiff music scene and have our sights set beyond…

To screen or not to screen? An evidence-based review and proposal for a 4-tier model for scoliosis screening in the UK
J. A. (Josette) Bettany-Saltikov
Scoliosis school screening is either mandatory or recommended in 32 states in the USA. The remaining states having either got voluntary screening or no recommendations. The four primary care providers for adolescents with idiopathic scoliosis in the USA do not support any recommendation against scoliosis screening, given the available literature. In Australia a national self detection program is implemented but in the UK school screening has been abolished since the 1980's. Opponents to scoliosis screening have focused on concerns about a low predictive value of screening, the cost effectiveness of referral, the possibility of unnecessary brace treatment and the effect of exposure to radiation when radiographs are obtained. The purpose of this review was to evaluate the evidence for and against scoliosis screening.

N2 - Scoliosis school screening is either mandatory or recommended in 32 states in the USA. The remaining states having either got voluntary screening or no recommendations. The four primary care providers for adolescents with idiopathic scoliosis in the USA do not support any recommendation against scoliosis screening, given the available literature. In Australia a national self detection program is implemented but in the UK school screening has been abolished since the 1980's. Opponents to scoliosis screening have focused on concerns about a low predictive value of screening, the cost effectiveness of referral, the possibility of unnecessary brace treatment and the effect of exposure to radiation when radiographs are obtained. The purpose of this review was to evaluate the evidence for and against scoliosis screening.

The recent cuts to veteran pensions, military pay, and personnel reduction initiatives (due to sequestration), have sparked an unexpected movement in the American armed forces. This chain of events has been marked as: The Air Force Hunger Games. Some also like to call it, The Air Force retention games. After the announcement of these reduction force programs, the AF/Hunger Games meme's came out of left field. This may seem like a joke, but people are very serious about the current state of affairs in the military. Thus the term: U.S. military Catching Fire. Let this be a testament of art imitating life. We can always find a way to connect the two. But why the comparison to The Hunger Games?
Members want to fight against a flawed system.
Members demand their voices be heard.
Those forced out under these new programs could be left scrambling just to survive.
This is a perfect example of art imitating life. Thousands of lives hang in the balance because the government does not know how to manage their money. The Military defense needs to clean up a 20 billion dollar deficit, and they have solved this deficit problem by gathering as many airmen as they can and forcing them to separate involuntarily. Thus disrupting livelihoods, and much like the 12 districts in the Hunger Games films, leaving many lives to hang in the balance.
The Hunger Games as a whole enforces the idea of rebellion, and revolution. While that is against Military law, young officers and enlisted have gravitated toward THG series for what it represents. They have shown their resistance in other ways and rightfully so. As a whole, the men and women who volunteered to lay down their lives for this country on a daily basis deserve better.
As a whole, the programs set in place guarantee, no matter how many years they have served in the Military, you have 70% chance of being jobless. A small percentage of those separated may separate with some incentives intact. Others will leave involuntarily with nothing. This is why the phrase, "May the odds be ever in your favor," resonates loudly throughout the services. Military and Veterans alike are rightfully angry and they are definitely speaking their minds about the issue.
As a member of the Air Force for the last 6 years, let me be the first to say individuals that serve in the armed forces are not rich. We simply do not make as much money as people think we do. Much like those living in the districts in the Hunger Games saga, many are just struggling to get by.
This an Air Force coin. All the services have their own versions. Coins are used to commemorate acts of service or valor and are normally presented by a higher authority. At the top is are pictures of what a typical Air Force coin looks like. Someone has made their own Hunger Games coin. You know its serious when there are meme's!
The Air Force Emblem, in the place of the MockingJay.
In this article, I discuss a small piece of a very large and on-going issue. This will be a challenging time for all military members of the armed services. I encourage everyone, to research more and discover more for themselves. if you have questions. If you want more information about the Air Force personnel reduction programs, please click HERE.

Seriously, many privately owned RV's just want help making their payments. They are serving a corporate board of directors demanding P&L statement. They can be more flexible with their schedules, pricing and just every day dealings.
Corporate RV's are usually maintained pretty well but they are also kind of generic.
Corporate rentals are 'No Frills'.
Private owners usually include many of the necessities that corporate fleets will charge for. Folding chairs, on board dvd's, towels, blankets, and anything else they can think of to make a profit.
Renting from a private owner means service NOW. Not when we get around to it.
Private owners pick and choose who rents their motorhome, They have a right to refuse service to anyone not meeting their demands.

Honda has confirmed that an affordable hybrid car will be available in the Indian markets by 2021. It is launching 6 models with conventional powertrains. Currently, the next big Honda model to launch is the Civic sedan.
Just yesterday, Honda Car India launched the 2018 Honda CR-V. The full-grown premium SUV is now a 7-seater SUV with a new diesel engine. The CR-V competes against the likes of Toyota Fortuner and Ford Endeavour. After the CR-V, the next big launch is the upcoming Civic sedan. Latest in the news is that the automaker is also planning to launch an affordable hybrid car in the Indian market. It will be much cheaper than the Camry Hybrid and is going to hit the markets before 2021.
A couple of weeks back, we reported that 2020 Honda City might get a mild-hybrid petrol variant. Currently, Ciaz comes with a mild-hybrid system. The next-generation of City is going to launch in 2020 itself.
With this, the automaker has said that total 6 models with conventional powertrain will be for the Indian markets. All of them will arrive in the market by the next 3 years. We expect new generations of Brio, Jazz and Honda City. Along with it, there might be some new models like the HR-V and such.
Honda has confirmed to ET that it would not be a fully electric vehicle and a normal hybrid. HCIL President and CEO Gaku Nakanishi also said that it is important to provide some incentives to the customers to motivate them for the upcoming EVs.
We do not have any other detail about this new hybrid car. It might be an all-together new car or based on some model from its current lineup.
Besides this, the automaker has confirmed that it will invest over Rs 9,200 crore for setting up a new factory for development of hybrid and electric vehicles. It will be a 380 acres factory in Gujarat, after one factory in Greater Noida and another in Rajasthan.
In the US and Japanese markets, it already sells its EV range under the Clarity brand. The range includes full-electric, fuel-cell and hybrid options. Well, there is a lot of time for full-electric and fuel-cell vehicles to come to India.
The Indian Government has started working on EV subsidies and lowering the rates on equipment related to EVs. Recently, it announced that people will get subsidies on purchasing EVs, depending on the price range. Also, the Indian Government has lowered GST rates on the purchase of after-market Lithium-ion batteries.

One of the hottest (and we mean temperature-wise!) beaches in Mexico.
From Playa Bush Beach, you can see the nearby South Point Lighthouse; it�s within hiking distance of the beach, if the day is not too hot, and it�s a pleasant walk to a photogenic spot. This is the beach where you�ll need a broad-brimmed hat and sunscreen, especially from ten in the morning until about three in the afternoon.
The beach operations folks try to combat the heat by providing rope hammocks strung up beneath a wood trellis, but all agree that the best way to beat the heat is to relax with a cold Corona beer at the bar or sit chin-deep in the ocean (or both!).
The beach bar and restaurant on Playa Bush Beach has a Rastafarian theme, with the colors of Jamaica painted around the palm tree trunks; the restaurant plays mostly Bob Marley music on its stereo, and it�s sometimes hard to remember that you�re really in Mexico!
Nearby, blowholes spout like the spray from whales and entertain for hours as they puff and spurt every few minutes when the tide is high. This provides for many giggles for children and adults alike.
Things seem to move more slowly at Playa Bush Beach than anywhere else on Cozumel. Some believe its just that time has been arrested and life has taken the lazy route, but it might just be the intense heat and the dizziness the sun can create when it makes you deliriously content. The trick is always recreating that sensation when you are back home.

BTOB hopes 'Outsider' will encourage people to be themselves
South Korean boy band BTOB is back Monday with a special album containing six songs, including the title track "Outsider."
A neo funk/neo soul style song with lyrics co-written by two of the group's members, Minhyuk and Peniel, "Outsider" encourages listeners to break free from the frustrations of daily routines and worries and boldly live the life they want to live.
This photo, provided by Cube Entertainment, shows BTOB in the "Silent" version of a teaser image for its new album "[4U : OUTSIDE]." (PHOTO NOT FOR SALE) (Yonhap)
"We used the word 'outsider' in a different sense from the conventional meaning," Minhyuk said during an online press meeting promoting the release of the new album, "[4U : OUTSIDE]."
"Ultimately, it's a song of healing," Changsub, one of the lead vocalists, weighed in. "BTOB are singers who give comfort."
The once seven-member group has currently been reduced to four, with Hyunsik and Sungjae carrying out their mandatory military service and Ilhoon having left the group in December amid allegations of drug abuse.
Through the special album, Eunkwang, Minhyuk, Changsub and Peniel try to show their new sides both in terms of musical depth and physical appearance.
The group recently performed in "Kingdom: Legendary War," an Mnet competition show featuring five other K-pop boy bands, which helped expand the band's "spectrum," according to Changsub.
"We wanted to show that wider spectrum in the new album," he said. "Not only as a group with stronger vocals but also as professionals on the stage."
Moreover, the album's teaser images were taken under two contrasting concepts: "Silent," composed of black and white images with chic, sensual and sexy vibes, and "Awake," a color version invoking natural and relaxed feelings.
Asked to describe what is unique about the new album, Changsub said it is the way in which each of the six tracks offers something different for each circumstance and mood.
"None of the colors are the same," the 30-year-old said. "If you're depressed, listen to 'Can't Breathe.' If the sun's shining and you feel like going somewhere, listen to 'Traveler.' If you feel trapped in a place with lots of people, listen to 'Outsider.' Listen to whatever you want, whenever you want."
Next year marks 10 years since the group's debut. Asked what they look forward to the most, Changsub replied, "A 10-year anniversary concert."
"I earnestly hope that we'll be free from COVID-19 and be able to sing together face to face, passing around the mic."
"[4U : OUTSIDE]" is set for release on music streaming sites at 6 p.m. (Korean time).

Supernatural's Top 15 Episodes
A breakdown of the most imaginative chapters in the show's 15-season run
Supernatural (The CW)
Michael Roffman, Jenn Adams and Nathan Smith
October 8, 2020 | 12:00am ET
Supernatural could never end. Sure, the show ceases to exist without Jensen Ackles and Jared Padalecki, but as long as they're still alive and kickin' it, the show goes on. Hell, the two stars could be 85 years old, sauntering around with nurses, and you could still find a way to make it work. That's the power of this series, and also a testament to its seemingly infinite sandbox — the best in the business, come to think of it.
None of this is hyperbole. For 15 years, the long-running CW series has run the gamut and back when it comes to world-building. We've seen Sam and Dean Winchester ascend to heaven, discover other worlds than these, join the Scooby gang, play themselves, attend Supernatural fan conventions, and flip through channels. At some point, the depths of hell become so commonplace, the two treat the place like a rest stop.
There have been rough patches, sure. Season 6 takes some time to find steadier footing after series creator Eric Kripke concluded his five-season run. And, yeah, Season 12 struggles to find conflict after, well, seeing God throw down. But, the writers always find another misadventure for the two Winchesters to solve, even if it's something as obvious as staging an entire episode in their car. They make it work.
Even now, this team just can't quit. During their recent interview with Variety, Ackles and Padalecki admitted that they have another idea for an episode — one they just couldn't fit into Season 15. "We called it Naked Supernatural," Ackles admitted. "It was like the Naked Gun version of Supernatural. Everything that happened in the episode would have been tongue-in-cheek." Fans are already demanding it.

Jensen Ackles Teases More Supernatural: "I Do Feel Like This Isn't the Long Goodbye"
Odds are they'll see it come to fruition. Again, there's just no end in sight for the Winchesters, and that's not because the creators are trying to exploit something and ruin a good thing. No, it's because it's too good a thing to walk away from — even after 15 years and 15 seasons. The fact that the creativity keeps coming speaks volumes about the series as a whole, and says even more about the characters in question.
They're family, we're family, and it's been one long family road trip ever since the show premiered on Tuesday, September 13, 2005. Let that date sink in. Try to imagine all the things that have happened since then: the places you've seen, the people you've met, the culture we've experienced. That should help contextualize the road so far, and add some weight to the entire journey. Will it end in November? Who knows.
All we can do is carry on.

15. "The Curious Case of Dean Winchester"
The Road So Far: Stalled on trying to halt the Apocalypse, the Winchesters do what they do best: save people and hunt things like malevolent presidents, powerful children, and old foes.
Now: The Winchesters roll into a town to probe the peculiar death by old age of a 25-year-old man. Bobby (Jim Beaver), Sam (Padalecki), and Dean (Ackles) then stumble upon a poker game where players can win big, but the stakes are even bigger. In this game, you bet years off your life, and both Bobby and Dean find themselves on the losing side of the game.
Carry On: Ah, there's nothing better than a good ol' poker flick. Maverick, Rounders, Casino Royale, The Gamber — with James Caan, of course — all boil down to one thing: the stakes. The sweatier the stakes, the better the game, and for Supernatural, writers Sera Gamble and Jenny Klein truly subverted the medium by tossing in a little Benjamin Button action. It's one of the more brilliant conceptual marriages in the show's history, toeing the line between comedy and intrigue as we watch Dean go grey.
None of it would work if it weren't so tightly wound. Gamble and Klein tie all the threads efficiently, from the story-of-the-week backstory involving Patrick (Hal Ozsan) and Lia (Pascale Hutton) to Bobby's ensuing arc involving his own physical ailments. It's razor sharp genre writing that affords the entire cast to flip the board. The greatest swap is seeing an elder Dean huff and puff behind an in-control Sam, who channels his inner Caan as he gambles his own life for the house. It's funny, it's gripping, it's a diamond one-off.
Team Free Will: Ackles reunites with his former Dawson's Creek pal in Ozsan. Also, we get a good look at Dean as an old man via Medical Center veteran Chad Everett. How about that.
14. "Moriah"
The Road So Far: The young Nephilim Jack (Alexander Calvert) has gone too far, killing Mary in a blast of anger. Sam, Dean and Castiel have locked him up in the Ma'lak Box in an effort to contain him – but it doesn't work and now he's free.
Now: Sam and Dean are on the hunt for Jack, who is causing chaos around the world by forcing people to "stop lying." Elsewhere, Chuck (Rob Benedict) appears with a weapon too good to be true, the Equalizer. In a classic Supernatural catch-22, the weapon promises to kill Jack, but also vanquish the individual that wields it. Naturally, the ensuing confrontation changes everything forever.
Carry On: The title "Moriah" comes from the Book of Genesis — specifically, chapter 22, verse two — and reads, "And He said: 'Take now thy son, thine only son, whom thou lovest, even Isaac, and get thee into the land of Moriah; and offer him there for a burnt-offering upon one of the mountains which I will tell thee of." So, it's not particularly hard to parse out what showrunner Andrew Dabb was thinking when he chose this title for the season finale. After all, Jack has become like a surrogate son to Dean, and these last few episodes have been winding up to Dean being forced to kill Jack — an act he cannot bring himself to commit.
Beyond that drama, the revelation that Chuck, aka God, has been orchestrating all their misery for their entire lives is quite the game-changer for Supernatural. It turns God from an absentee father of a benevolent nature to one of a malevolent force that actually makes quite sense when you consider the long-game storytelling. Narratively, the twist breaks the fourth wall in a different way, dissecting the agency the characters have when they're being written by someone. They don't want the pain that's being thrust upon them, and that's the key to it all – it's finding the will to fight against what's already been written.
More importantly, if we drill down deeper, God's love of putting the Winchester brothers through pain and suffering is a commentary on the audience who watch Supernatural. They, too, love it when the Winchesters experience loss and heartache. It's a narcotic to the fans and the cheapest one on the market – the written word.
Team Free Will: Benedict reprises his role as Chuck/God here, while Lisa Berry returns as the formidable reaper, Billie.
13. "The Real Ghostbusters"
The Road So Far: The Winchesters meet their biggest fan, a fan fiction scribe named Becky Rosen (Emily Perkins). They also discover that one of their oldest nemeses, the Trickster (Richard Speight Jr.), is actually the archangel Gabriel.
Now: Becky uses Chuck's phone to trick the Winchesters into showing up at a convention for the Supernatural books. Unfortunately for the cosplaying con-goers, a real poltergeist shows up on scene and begins making violent trouble.
Carry On: "The Real Ghostbusters" is a love letter to fans, and one of a handful of meta episodes in the show's catalogue. Taking place at the first-ever Supernatural convention, it's a hilarious look at the series from the perspective of its viewers — but also through and Dean and Sam.
Naturally, the two brothers are understandably shocked to see people cosplaying them, talking in gruff voices, and even reenacting personal conversations between the two brothers. And while the episode pokes fun at fan culture with its nitpicking questions and analytical theories — "Frightened Little Boy – the Secret Life of Dean Winchester" and "The Homoerotic Subtext of Supernatural", anyone? — writers Kripke and Nancy Weiner never shame the fans. Instead, they explore the uplifting power of fictional characters.
Two such characters Barnes (Ernie Grunwald) and Damien (Devin Ratray) steal the show as partners and con-goers inadvertently roped into helping Sam and Dean on the LARP Ghost Hunt that veers a little too close to reality. What's more, their touching moment at the end of the episode is a nice step toward inclusiveness on a show working towards diversity. Meanwhile, Prophet Chuck gets a hero moment, and No. 1 fan Becky Rosen is fantastic, creepily ogling Sam before "dumping" him for Chuck. And lest we forget, it's all set against the backdrop of a truly creepy ghost story. Who wouldn't want that?
Team Free Will: This episode features post credits ad lib by Benedict as Chuck; the second appearance of Perkins as Becky, and the first mention of the demon Crowley (Mark Sheppard).

12. "The Monster at the End of This Book"
The Road So Far: Sam and Dean are embroiled in an all-out war involving angels and demons, only to learn from a new angel on the block, Zachariah, that they cannot escape their fate.
Now: While Lilith makes her final moves, Sam and Dean stumble upon a series of novels that detail all the trials and tribulations in their life called Supernatural, all written by a man called Carver Edlund.
Carry On: By Season 4, the series was already waist-deep in meta humor, mostly thanks to the arts and crafts provided by the Trickster (Speight Jr.). Even so, "The Monster at the End of This Book" still felt like a total game changer by acknowledging the then-budding fan base without losing any steady ground. Writers Julie Siege and Nancy Weiner did their homework, too, managing to even squeeze in a reference to the online Slash fiction that has become a curious part of the show's legacy.
More importantly, though, Siege and Wiener opened up another door for the series creatively. Looking back, there's a lot of table-setting in this episode, and the idea that Supernatural was an in-world entity helped condition later concepts like alternate universes, animated crossovers, and even the inclusion of Oz. Not to mention, it also introduced arguably the most important character of the series beyond Sam and Dean: Carver Edlund (Benedict), aka Chuck, aka God.
It's through Chuck that Supernatural became what it is today, and his introduction is seamless. Christ, Benedict plays the role with so much burden and conviction that you really do believe he's this exhausted Prophet of God — even when he literally says: "Obviously I'm a God… I write things and then they come to life. Yeah, no, I'm definitely a God. A cruel, cruel, capricious god." Granted, fans sniffed out his true identity long before Season 11's "Don't Call Me Shurley", but hey, hindsight's 20/20.
Team Free Will: Well, as mentioned, Benedict joins the mythos. Keep up!
11. "LARP and the Real Girl"
The Road So Far: Dean, his vampire friend Benny (Ty Olsson), and Castiel (Misha Collins) have escaped Purgatory and the prophet Kevin is working to decipher a "demon tablet" in the hopes to banish all demons to Hell for good.
Now: A mysterious case involving a man being drawn and quartered drags the brothers into the world of Live Action Role Playing and back into the company of the fiery, friendly computer hacker, Charlie Bradbury (Felicia Day).
Carry On: "LARP and the Real Girl" sees the return of fan favorite Charlie Bradbury, aka the Queen of Moons, lead a group of LARPers (or Interactive Literaturists) living out their medieval fantasies in attempt to escape the mundanity of their lives. While Sam is mostly dismissive of the concept, Dean is into it, offering Charlie tips on the battlefield and enjoying his new role as Handmaiden. True to form, Charlie is a non-traditional queen, wearing battle clothes, sparring with squires on the pitch, and even rescuing the damsel in distress. Eventually, she saves the day by destroying the book of spells and freeing the fairy that caused all the mayhem, even making out with said fairy before she returns to her magical realm.
But there's a flip side to this coin: While all the participants take their roles seriously, writer Robbie Thompson presents a darker side of this world through the episode's villain Gerry (Hank Harris), Boltar the Furious. Unlike Charlie and her friends, Gerry is someone who takes the game so seriously he is willing to murder his friends for an imaginary role. It's an important commentary on escapism taken too far and the ensuing toxic fandom that tends to poison any fan culture. But there's a tangential lesson to also be learned when Sam and Dean are mistaken for FBI LARPers: Like Charlie's crew, they chose to be hunters, a life that gives them more purpose and fulfillment than the "normal" lives they've both tried to lead.
On a side note: Special shoutout to the Braveheart reenactment concluding the episode. It may be the only speech Dean knows, but it's the perfect ending to a fun and empowering episode.
Team Free Will: This episode is the second appearance of Charlie after she was last seen in the Season 7 finale, The Girl with the Dungeons and Dragons Tattoo.
10. "Ghostfacers"
The Road So Far: Dean has sold his soul to a crossroads demon who gave him one year before his time would be up. The demon that plans to collect on Dean's soul, Lilith, has made her presence known in a violent, explosive way.
Now: Sam and Dean find themselves trapped alongside the twerpy, ghost hunting duo of Ed Zeddmore (Travis Wester) and Harry Spengler (A.J Buckley) and their gaggle of goons as they seek to investigate and stop a vicious poltergeist in the most haunted place in America, The Morton House, the events of which are told via the "unsolicited" reality television pilot, Ghostfacers.
Carry On: In the Season 3 book companion for Supernatural, the writers talk a lot about how the 2007-08 WGA strike affected how they chose to plot episodes out. In the case of "Ghostfacers", it involved putting the Winchesters in a position where they wind up as second bananas on their own show. Not surprisingly, given writer Ben Edlund's involvement, the episode is rife with wisecracks, be it the constant bleeps on account of the brothers' constant profanity or the 'Facers calling the Winchesters hicks when the boys show up to the scene blaring Grand Funk Railroad's "We're an American Band". What's more, Wester and Buckley have crackerjack chemistry and work so well as competent doofuses.
Despite the litany of chuckles on display, the episode delivers on its promise of spooky fare. The concept of death echoes is introduced, which finds specters fated to relive their death over and over again. So, that's terrifying. Also eerie is the main villain, Freeman Daggett, who steals bodies from the morgue he worked at when he was alive and uses them to create his own little sick soiree. This leads to a disturbing scene where Daggett murders novice Ghostfacer Corbett (Dustin Milligan), all while Sam looks on in horror – the skipping record playing Lesley Gore's "It's My Party" is the cherry on top of the creep cake. This arc even manages to find room for a sweet little moment between Ed and Corbett, who shows romantic affection for him.
All in all, it's a very versatile hour of television.
Team Free Will: Buckley and Wester make their first appearance since Season 1's "Hell House". Milligan would go on to be the kindhearted vet, Ted, on the popular Canadian program Schitt's Creek.
09. "The French Mistake"
The Road So Far: Sam and Dean are out fighting a new breed of monsters called Alphas. Meanwhile, a civil war has broken out in Heaven, led by the archangel Raphael (Demore Barnes).
Now: In an effort to keep the brothers safe from angel hitman Virgil (Carlos Sanz), their ally Balthazar (Sebastian Roché) zaps the Winchesters into an alternate universe, where Sam and Dean are respectively known as Jared Padalecki and Jensen Ackles and are starring on a television series called Supernatural.
Carry On: "The French Mistake", named so for the meta ending of Mel Brooks' Blazing Saddles, is hardly the first or last time that Supernatural would break the fourth wall. This time around, though, the series' reliable scribe Ben Edlund fired a double-barrel shotgun blast of salt straight at the barrier between the characters and their audience.
This break allowed both Padalecki and Ackles to erase any semblance of "vanity" by picking apart their on- and off-screen personas. Together, they poked fun at Jensen's early career soap opera roles, Padalecki's romantic life, their supposed dislike for each other, the implied creative bankruptcy of the crew (Season 6 is used as a constant, exasperated refrain), and the show's rabid, oft-toxic fanbase.
Though the episode is wrapped up tightly in Season 6's overarching grim mythology, there's some hilarious bits here — you know, like the riotous montage of "Sam" and "Dean" acting terribly. It's also nice to see the normally dour, restrained Misha Collins being allowed to stretch his wings, pun intended, as a dopey tweeting twerp. It's even funnier when you realize that all the tweets he sent out in the episode, he actually tweeted when the episode originally aired.
It doesn't get more meta than that.
Team Free Will: Genevieve Padalecki returns to the series, but this time playing herself. Brian Doyle-Murray guests playing the show's longtime director/producer Robert Singer.

A. (E)-4-Dimethylamino-3-buten-2-one , 1.2 A 250-mL, round-bottomed flask equipped with a magnetic stirring bar is charged with acetylacetaldehyde dimethyl acetal (Note 1) (19.8 g, 0.15 mol), freshly distilled prior to use (67°C, 12 mm). A 2.0 M solution of dimethylamine in methanol (Note 1) (85 mL, 0.17 mol) is then added in one portion. The resulting yellow solution is stirred at room temperature for 4 hr, and concentrated on a rotary evaporator. The resulting oil is purified by bulb-to-bulb distillation (0.25 mm, oven temp 100-120°C) (Note 2) to afford 15.3 g (90%) of the desired vinylogous amide as a pale-orange oil (Note 3).
B. (E)-1-Dimethylamino-3-tert-butyldimethylsiloxy-1,3-butadiene , 2. A dry, 500-mL, three-necked, round-bottomed flask is equipped with a pressure equalizing addition funnel, a large egg-shaped magnetic stirring bar, and a nitrogen/vacuum adapter. The apparatus is evacuated and flushed with nitrogen. The flask is charged with a 1.0 M solution of sodium bis(trimethylsilyl)amide (NaHMDS) in tetrahydrofuran (THF) (Note 1) (100 mL, 0.100 mol) and the flask is cooled in a dry ice-acetone bath (−70°C bath temp), causing a viscous, yellowish-white suspension to form. To this suspension is added, over a period of 30 min via an addition funnel, a solution of (E)-4-dimethylamino-3-buten-2-one (11.3 g, 0.100 mol) in THF (50 mL). The funnel is rinsed with a small amount of THF, and the resulting clear-yellow solution is stirred for 1.0 hr at −78°C. A solution of tert-butylchlorodimethylsilane (Note 4) (15.8 g, 0.105 mol) in THF (50 mL) is added over a 5-min period, via an addition funnel. The funnel is again rinsed with a small amount of THF. The cooling bath is removed and the reaction mixture is allowed to reach room temperature, which requires about 1.5 hr. The reaction mixture is poured into a 1-L Erlenmeyer flask containing 600 mL of anhydrous ether (Note 5). The resulting suspension is allowed to stand for 30 min and then suction filtered through a pad of dry Celite (60 g) (Note 6) packed in a 600-mL sintered glass filter funnel (Note 7). The filter cake is washed with three 50-mL portions of ether (Note 8), and the filtrate is concentrated on a rotary evaporator (heating bath temp <45°C). The resulting dark orange oil, containing the diene and hexamethyldisilazane, is subjected to bulb-to-bulb distillation (110-120°C, 0.3 mm) (Note 9) to yield 20.4 g (90%) of the desired 1-amino-3-siloxy-1,3-butadiene (Note 10) as a light-yellow oil (Note 10).
1. This reagent was purchased from the Aldrich Chemical Company, Inc.
2. The receiver bulb was cooled with ice as soon as the product started to distill.
3. On occasion the vinylogous amide was obtained as a dark oil, but exhibited good spectroscopic properties. A cleaner-looking sample of the product was obtained by resubjecting the dark oil to bulb-to-bulb distillation. The checkers used a coffee-maker bulb-to-bulb distillation apparatus and recorded a bp of 60-80°C at 0.1 mm. Characterization data follow: IR (neat) cm−1: 1660, 1575, 1436, 1356, 1258, 1112, 962 ; 1H NMR (300 MHz, CDCl3 ) δ: 2.10 (s, 3 H), 2.88 (br s, 3 H), 2.99 (br s, 3 H), 5.05 (d, 1 H, J = 12.8), 7.47 (d, 1 H, J = 12.8) ; 13C NMR (75 MHz, CDCl3 ) δ: 28.0, 36.9, 44.5, 96.6, 152.6, 195.2 ; mass spectrum (EI) 113 (C6H11NO), 98 (base) .
4. This reagent was purchased from Lithco, a division of the FMC Corporation.
5. Anhydrous ether was purchased from Fisher Scientific Company and used without further purification.
6. Celite 545 was purchased from Fisher Scientific Company and was flame-dried under vacuum just prior to filtration. The Celite was packed tightly into the funnel using the bottom of a beaker.
7. A sintered-glass Büchner funnel having a C-porous frit was employed.
8. When the filtration became very slow, the filter cake was stirred with a spatula to break up the pasty layer on top. The filtration must be done carefully to minimize transfer of sodium chloride (NaCl) to the filtrate. Lower yields of less pure product are obtained if considerable amounts of NaCl are present during the subsequent distillation. If a gel is obtained after removal of solvent on the rotary evaporator, too much NaCl is present.
9. A 250-mL flask is used as the pot, connected to a 100-mL collection bulb, connected to a cold trap (dry ice-acetone) to protect the vacuum pump. Hexamethyldisilazane is collected first in the cold finger (−78°C). Then, as soon as the diene starts to distill, the collection bulb is cooled with ice. The checkers recorded a bp of 60-80°C at 0.07 mm.
10. The diene displays the following spectral data: IR (neat) cm−1: 1648 ; 1H NMR (500 MHz, CDCl3) δ: 0.19 (s, 6 H), 0.98 (s, 9 H), 2.70 (s, 6 H), 3.84 (s, 1 H), 3.92 (s, 1 H), 4.78 (d, 1 H, J = 13.2 ), 6.57 (d, 1 H, J = 13.2) ; 13C NMR (75 MHz, CDCl3) δ: −4.6, 18.3, 25.9, 40.5, 85.8, 95.9, 140.9, 156.4 ; mass spectrum (EI) 227 (C12H25NOSi), 156 (base) . This material contains trace impurities by 1H and 13C NMR.
11. The submitters report that an alternate purification method involves distillation through a micro short-path distillation apparatus fittted with a Vigreux column (10 cm). Under this protocol, diene 2 (bp 60°C at 0.5 mm) is obtained as a clear, colorless liquid in 82% yield. (This modification was not checked).
Aminosiloxy dienes are highly reactive in Diels-Alder reactions, considerably more so than the analogous dialkoxy dienes.5a, 9 They undergo [4+2] cycloadditions with a broad range of electron-deficient dienophiles.5,7 The reactions generally occur under very mild conditions and afford the corresponding cycloadducts in good yields and with complete regioselectivity. A full study on the preparation and cycloadditions of amino siloxy dienes has been carried out.7 In the procedure that follows, a preparative scale procedure is described for the Diels-Alder reaction of an aminosiloxy diene, reduction of the electron-withdrawing group in the adduct, and hydrolysis of the β-aminoenolsilyl ether moiety to the 4-substituted cyclohexenone.
