Resolution and synthesis of optically active alcohols with immobilized water-soluble proteins from green pea, soybean and buckwheat as new bio-catalysts.

Kinetic resolution of racemic alcohols, (+/-)-1-(4-substituted phenyl)ethanol and (+/-)-1-(2-naphthyl)ethanol, was done with immobilized green pea, soybean, or buckwheat proteins. The resolution was done stereoselectively by oxidizing only one enantiomer of a racemic alcohol to leave an optically active alcohol with a high purity. In addition, each protein could be reused consecutively at least three times without any decrease of yield or optical purity.
