A method for producing optically active glycol derivatives by biochemical resolution which comprises contacting a racemic ester of the general formula 1 ##STR1## (wherein R.sub.1 is an aliphatic hydrocarbon group of 1 to 16 carbon atoms, R.sub.2 is an aliphatic hydrocarbon group of 1 to 8 carbon atoms, and R.sub.3 is an aromatic hydrocarbon group such as phenyl, tolyl or naphtyl) with a microorganism- or animal organ-derived enzyme having stereoselective hydrolytic activity to asymmetrically hydrolyze said racemic ester of general formula 1 to produce an optically active alcohol of general formula 2* ##STR2## (wherein R.sub.1 and R.sub.3 have the same meanings as defined above) and an unreacted ester of the general formula 1* ##STR3## (wherein R.sub.1, R.sub.2 and R.sub.3 have the same meanings as defined hereinbefore), separating the optically active compounds from each other, hydrolyzing said ester of general formula 1* to give an optically active glycol derivative which is antipodal to the alcohol of general formula 2* and, then, isolating the same optically active glycol derivative. The invention provides a method for producing optically active glycol derivatives, which is expedient, does not require costly reagents and is suited to commercial scale production.
一种通过生物化学拆分制备光学活性乙二醇衍生物的方法,包括将一般式1的外消旋酯(其中R.sub.1是1到16个碳原子的脂肪烃基,R.sub.2是1到8个碳原子的脂肪烃基,R.sub.3是芳香烃基,如苯基、甲苯基或萘基)与具有立体选择性水解活性的微生物或动物器官来源的酶接触,使得外消旋酯1按照不对称方式水解成为一般式2*的光学活性醇(其中R.sub.1和R.sub.3的含义与上文定义相同),以及未反应的一般式1*的酯(其中R.sub.1、R.sub.2和R.sub.3的含义如前所述),分离出光学活性化合物,水解所述的一般式1*的酯以得到一种与一般式2*的醇对映的光学活性乙二醇衍生物,然后,分离出相同的光学活性乙二醇衍生物。该发明提供了一种制备光学活性乙二醇衍生物的方法,这种方法方便、不需要昂贵的试剂,并适合商业规模生产。
