The asymmetric synthesis of 1-[2-hydroxy-3-(4-phenyl-1-piperazinyl)-propyl]-pyrrolidin-2-one 1 is described. Enantiomers of compound I were obtained using the Sharpless asymmetric dihydroxylation (AD) or hydrolytic kinetic resolution (HKR) methods. The enantiomers of compound 1. which were obtained by HKR had higher enantiomeric excesses than those which were synthesized by AD and epoxidation. The enantiomeric purity of the synthesized compounds was determinated by capillary electrophoresis. (C) 2001 Elsevier Science Ltd. All rights reserved.
