Versuchsvorschrift

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.
