。The optically active α-hydroxyketone obtained in the present invention is converted into a sulfonic acid ester, and then subjected to a stereospecific rearrangement reaction to be substituted with an optically active α-aromatic group, which is a main component of non-steroidal anti-inflammatory analgesics, synthetic pyrethroids, etc. It is derived from carboxylic acids, -monoaromatic group-substituted alcohols, and the like. Many of these compounds have low efficacy or are completely absent in racemic form, and are required to be optically active, but at present, no suitable manufacturing method is known.

0.5〜5チか好ましい。The asymmetric hydrolysis reaction can be carried out by adding a-hydroxyketone carboxylic acid ester as a substrate at the same time as inoculating the inoculum or after the bacteria have grown, or by incubating the bacterial cells that have grown by culturing in advance in an appropriate buffer. Any method may be used, such as a method in which the esterase is suspended in water, a substrate is added thereto, and cultured, or a method in which the esterase produced by the image is purified by a conventional enzyme purification method, and then added to the substrate and cultured. The culture temperature may be any temperature that allows the growth of bacteria, and 25 to 35°C is usually optimal for rapid growth. Cultivation time varies depending on the type and concentration of substrate, culture temperature, etc., but usually takes 2 hours to 7 days. The concentration of the substrate is generally about 0.1 to 10%, preferably about 0.5 to 5%.

This is washed twice with 50-liters of distilled water and further washed with cold acetone, and then stored in a freezer. Two shaking flasks of frozen bacterial cells were treated with 2-hydroxy-1-phenyl-1-sitanone acetate (2-hydroxy-1-phenyl-1-sitanone acetate) 106.9■ in the same manner as in Example 6, and then a separation operation was performed to obtain *f.
