It is an objective of the present invention to produce an anti-form of an optically active β-hydroxy-α-aminocarboxylic acid ester efficiently, simply and industrially advantageously. The objective can be accomplished by directly and selectively producing the anti-form of the optically active β-hydroxy-α-aminocarboxylic acid ester by asymmetric reduction of a β-keto-α-aminocarboxylic acid ester using an optically active amine complex as a catalyst. Further, the β-keto-α-aminocarboxylic acid ester as a raw material can be produced at a high yield by reacting a glycine derivative with a carboxylic acid derivative.
本发明的目的是高效、简单、工业上具有优势地生产一种光学活性的β-羟基-α-氨基羧酸酯的反式形式。该目标可以通过使用光学活性胺配合物作为催化剂,直接选择性地通过不对称还原β-酮基-α-氨基羧酸酯来生产光学活性β-羟基-α-氨基羧酸酯的反式形式来实现。此外,可以通过将甘氨酸衍生物与羧酸衍生物反应来高产地生产β-酮基-α-氨基羧酸酯原料。
