title: Synthesis of 2,4,6-trisubstituted chiral piperidines and (-)-dendroprimine by one-pot asymmetric azaelectrocyclization protocol.
abstract: [reaction: see text] Stereocontrolled synthesis of 2,4,6-trisubstituted piperidine diastereomers has been realized from common intermediates, obtained by a one-pot azaelectrocyclization protocol. Based on the method, the asymmetric synthesis of an indolizidine alkaloid, (-)-dendroprimine, was achieved.
