실험 절차

100 mM potassium phosphate buffer (pH 6.5), 139.8 mg NADH, 0.06 U (R)-2-octanol dehydrogenase from Candida utilis, and 0.5% 4-chloroacetoacetic acid ethyl ester were reacted overnight at 30° C. The optical purity of the 4-chloro-3-hydroxybutyric acid ethyl ester produced was determined in the same way as Example 32. As a result, 4-chloro-3-hydroxybutyric acid ethyl ester produced by this invention was more than 97% ee of S form.
