实验过程

To 0.02 g of the aforementioned wet bodies was added 500 μl of 50 mM phosphate buffer (pH 7.0) containing 1% 2,2,2-trifluoroacetophenone and 5% 2-propanol, followed by stirring at 30° C. for 18 hours. Then, after adding 500 μl of ethyl acetate to the reaction mixture, the mixture was subjected to centrifugal separation to obtain the organic phase. The organic phase was subjected to an analysis of the content by way of gas chromatography under the following condition. 2,2,2-Trifluoro-1-phenylethanol was produced at a ratio of 49.4% based on the amount of 2,2,2-trifluoroacetophenone used in the reaction. Furthermore, optical purity of 2,2,2-trifluoro-1-phenylethanol in the organic phase was measured under the following condition. The (S)-form of 99% e.e. was demonstrated.
