torquoselectivity can also apply to other mechanisms, including chiral lewis acid catalysts, induction by neighboring stereocenters (in which case the torquoselectivity is a case of diastereoselectivity), and axial-to-tetrahedral chirality transfer. an example of axial-to-tetrahedral chirality transfer is shown below for the torquoselective nazarov cyclization reaction of a chiral allenyl vinyl ketone.
