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.
本申请涉及一种生产光学活性α-氨基酸衍生物的方法,包括以下步骤:将由通式(1)表示的α-卤代酯衍生物与胺化合物反应;然后去保护所得化合物;进一步进行酯交换反应。根据本发明方法,可以轻松地生产出光学活性的α-氨基酸酯衍生物,该衍生物可用作具有高选择性的药物中间体。
