Optically active pipecolic acid derivatives can be prepared by the aza-Diels-Alder reaction of simple dienes with the imine derived from ethyl glyoxylate and chiral 1-phenylethylamine; the cycloadditions are regiospecific, highly diastereoselective within the heterocyclic ring (>92percent exo with cyclic dienes, and 100percent endo with acyclic dienes), and lead to high asymmetric induction in most cases (average d.e. = 72percent).
