Efficient preparation of optically pure 4-hydroxyalkanenitriles, la-f, was achieved via an enzymatic reaction using lipase PS (Pseudomonas sp.). Optically pure (R)-4-hydroxy-3-[[3,4-(methylenedioxy)phenyl]methyl]butanenitrile (1a) was applied to the enantioselective synthesis of three types of antitumor lignans, (-)-hinokinin, (-)-isodeoxypodophyllotoxin, and (+)-isostegane.
