Nomenclature of saturated aliphatic hetrocyclic amines with an alkyl group on the nitrogen

For example, how would I name the following amine?


[![1-propylpyrrolidine](https://i.stack.imgur.com/9DJhR.png)](https://i.stack.imgur.com/9DJhR.png)


Since two of the alkyl groups on nitrogen are linked to each other (in a ring), I can't figure out what they should be called, as they don't fit into the usual alkyl (methyl/ethyl/etc.) mould.




According to Subsection P-22.2.1 of the current version of *[Nomenclature of Organic Chemistry – IUPAC Recommendations and Preferred Names 2013 (Blue Book)](http://dx.doi.org/10.1039/9781849733069-fp001),* the preferred IUPAC name (PIN) of the functional parent compound is the retained name ‘pyrrolidine’, the nitrogen atom being numbered ‘1’.

Therefore, the name of the compound given in the question is ‘1-propylpyrrolidine’.

Without knowing what you have tried and where your specific trouble is, my guess is that you are having trouble identifying the parent chain.


This molecule is a heterocyclic amine, and the entire heterocycle is the parent chain. In this case, the parent chain is called **pyrrolidine**.

Now - how would you name a pyrrolidine with an alkyl substituent on the nitrogen atom?
