摘要：

Hydrocyanation of enantiomerically pure N-Cbz alpha-fluoroalkyl beta-sulfinylenamines 1 occurs smoothly by treatment with KCN or by addition of trimethylsilylcyanide or diethyl phosphorocyanidate to preformed sodium derivatives of 1. The diastereoisomeric difluoro alpha-aminonitriles 2b have been transformed in the unnatural amino acids (R)-alpha-difluoromethyl-alanine and (S)-alpha-difluoromethyl-serine.
