Abstract
Novel chiral glycinate derivatives (S)-6 and (S)-7 containing the a-phenylethyl group, were prepared and studied as potentialprecursors of enantiopure a-substituted-a-amino acids. In particular, the alkylation of enolate (S)-7-Li showed substantial (78:22 dr)stereoinduction by the N-(1-phenylethyl)benzamide chiral auxiliary.Addition of DMPU showed no appreciable effect upon the diastereoselectivity
