実験手順

As shown here, the biochemical conversion reaction of immobilized green pea protein for the substrate (±)-1-(4-chlorophenyl)ethanol (200 mg) requires 8 days by going through bioconversion to 4-chloroacetophenone accompanying sterically selective oxidation of (R)-1-(4-chlorophenyl)ethanol to obtain 84 mg of (S)-1-(4-chlorophenyl)ethanol at a yield of 42%. Optical purity was obtained at 87% e.e.
