A Convenient Method for Preparation of α-Imino Carboxylic Acid Derivatives and Application to the Asymmetric Synthesis of Unnatural α-Amino Acid Derivative
glycine derivatives for the synthesis of α-imino carboxylic acidderivatives. Using this methodology, utilization of unstable glyoxic acidderivatives was avoided. Furthermore, using this methodology we synthesized novel α-imino carboxylic acidderivatives such as α-imino phenyl ester, perfluoroalkyl etsers, imides, and thioester. The asymmetric Mannich reaction of those novel imine derivatives with 1
