A process for producing an optically active compound based on the hydrolysis of an alkenyl ester compound or the cleavage of an alkenyl ether compound. The process uses neither an acidic compound nor a basic compound, and rectants can be reacted in a high concentration. It does not necessitate a buffer, nutrient, etc. unlike enzymatic reactions or reactions using a microorganism. It is a simple process which attains a satisfactory production efficiency. The process, which is for producing an optically active carboxylic acid or optically active alcohol represented by the general formula (VI): (wherein R

一种基于烯基酯化合物的水解或烯基醚化合物的裂解制备光学活性化合物的方法。该过程既不使用酸性化合物也不使用碱性化合物,反应物可以在高浓度下反应。与酶反应或使用微生物的反应不同,它不需要缓冲剂、营养物等。这是一个简单的过程,可以实现令人满意的生产效率。该过程用于制备由通式(VI)表示的光学活性羧酸或光学活性醇,其特征在于在具有光学活性配体的特定过渡金属配合物存在下,使水作用于通式(I)表示的烯基酯或烯基醚(其中R4、R5和R6分别表示氢、烷基等)。
