METHOD OF PRODUCING OPTICALLY ACTIVE AMINO ACID DERIVATIVE

The present application relates to a method for producing an optically active α-amino acid derivative, comprising steps of reacting an α-haloester derivative represented by the general formula (1): of which alcohol part of the ester group is an optically active alcohol derivative, with an amine compound; then deprotecting the obtained compound; further carrying out an ester exchange reaction. According to the present invention method, it is possible to easily produce an optically active α-amino acid ester derivative which is useful as an intermediate for drugs with high selectivity.
