Abstract
A survey of conjugate additions of Yamamoto organocopper reagents to N -enoyl-4-substituted oxazolidinones is reported. Diastereofacial selec tivity is reversed for 4-phenyl and 4-benzyloxazolidinones of the same relative configuration. Alkenylcopper reagents demonstrate superior r esults in asymmetric additions using the 4-phenyloxazolidinone auxilia ry. (C) 1998 Elsevier Science Ltd. All rights reserved.
