实验步骤: As shown here, the biochemical conversion reaction of immobilized buckwheat protein for the substrate (±)-1-(4-bromophenyl)ethanol (200 mg) requires 11 days by going through bioconversion to 4-bromoacetophenone accompanying sterically selective oxidation of (S)-1-(4-bromophenyl)ethanol to obtain 114 mg of (R)-1-(4-bromophenyl)ethanol at a yield of 57%. Optical purity was obtained at 88% e.e.

实验步骤: As shown here, the biochemical conversion reaction of immobilized soy bean protein for the substrate (±)-1-(4-bromophenyl)ethanol (200 mg) requires 2 days by going through bioconversion to 4-bromoacetophenone accompanying sterically selective oxidation of (S)-1-(4-bromophenyl)ethanol to obtain 108 mg of (R)-1-(4-bromophenyl)ethanol at a yield of 54%. Optical purity was obtained at 88% e.e. Equipment conditions were the same as for immobilized green pea protein.

实验步骤: As shown here, the biochemical conversion reaction of immobilized green pea protein for the substrate (±)-1-(4-bromophenyl)ethanol (200 mg) requires 8 days by going through bioconversion to 4-bromoacetophenone accompanying sterically selective oxidation of (R)-1-(4-bromophenyl)ethanol to obtain 114 mg of (S)-1-(4-bromophenyl)ethanol at a yield of 57%. Optical purity was obtained at 88% e.e. The reaction course and time at completion of reaction were determined by GC using the Hitachi Model G-3500 gas chromatograph under conditions consisting of carrier gas: He at 0.48 ml/min, split ratio: 1/55, oven temperature: 150° C., inlet temperature: 250° C., outlet temperature: 250° C., pressure: 136, flow rate value: 42, analytical column: TC-5HT 0.25 mm I.D.×30M df (GL Science).

实验步骤: By using the equipment analysis described above, the retention times of (±)-1-(4-bromophenyl)ethanol were confirmed to be 10.447 for the S form and 11.031 for the R form, those of (±)-1-(4-chlorophenyl)ethanol 9.936 for the S form and 10.355 for the R form, those of (±)-1-phenylethanol 11.958 for the S form and 13.133 for the R form, those of (±)-1-(2-naphthyl)ethanol 15.693 for the S form and 17.049 for the R form, those of (±)-1-(4-methoxyphenyl)ethanol 9.165 for the S form and 10.781 for the R form, and those of (±)-1-(4-nitrophenyl)ethanol 18.923 for the R form and 19.562 for the S form. In addition, the retention times of 4-bromoacetophenone, 4-chloroacetophenone, 4-methoxyacetophenone and 4-nitroacetophenone that are formed by oxidation of each substrate were similarly confirmed to be 13.122, 10.304, 17.169 and 37.208, respectively.
