  The present invention provides a process for simply producing an optically active 2-thiomethyl-3-phenylpropionic acid derivative useful as an intermediate for medicines from inexpensive raw materials. An optically active 2-hydroxymethyl-3-phenylpropionic acid ester derivative which can be relatively easily obtained by asymmetric reduction reaction with an enzyme is cyclized to an optically active β-lactone derivative which is then reacted with a sulfur compound to produce an optically active 2-thiomethyl-3-phenylpropionic acid derivative in high yield.

  The present invention is to provide a process for simply producing an optically active 3-hydroxypropionic ester derivative useful as a medicament intermediate from an inexpensive material. More specifically, the present invention is directed to a process for producing an optically active 3-hydroxypropionic ester derivative comprising reacting an acetic ester derivative available at low cost with abase and a formic ester, thereby converting the acetic ester derivative into a 2-formylacetic ester derivative, and thereafter, stereospecifically reducing the formyl group of the derivative by use of an enzymatic source capable of stereoselectively reducing the formyl group of the derivative.

  本发明提供了一种简单制备光学活性的3-羟基丙酸酯衍生物，该衍生物可用作药物中间体，从廉价原料中制备。更具体地，本发明涉及一种制备光学活性的3-羟基丙酸酯衍生物的方法，包括将一种低成本的乙酸酯衍生物与碱和甲酸酯反应，从而将乙酸酯衍生物转化为2-甲酰乙酸酯衍生物，然后使用能够立体选择性还原该衍生物的酶源，立体特异性地还原衍生物的甲酰基。
