Abstract
The imine Ph2CHN=CHCO2Et, generated from benzhydrylamine and ethyl glyoxylate, provides a Diels-Alder adduct with 1,3-pentadiene from which a range of cis-2,6-disubstituted piperidines can be accessed; the benzhydryl group confers high diastereocontrol for derivatising the six-membered ring, allowing access to 2,5,6-trisubstituted piperidines, and to 2,6-disubstituted piperidines such as pinidine. © 2002 Elsevier Science Ltd.
