Method for producing stereoselectively and catalyst can be allowed to proceed Strecker reaction stereoselectively using the a-amino nitrile derivative α-

摘要

In accordance with the present invention, a method for producing stereoselectively and Strecker reaction catalyst consists of a quaternary ammonium salt using the a-amino nitrile derivative α- is provided. By using and obtained in the present invention the α- amino nitrile derivative, it can be easily manufactured and its derivatives α- an optically active amino acid has been difficult in the alkylation reaction of the prior art.
