摘要:
Enantioselective process for the preparation of the S enantiomer of an optically active cyanohydrin by reacting an aldehyde or an asymmetric ketone with a cyanide group donor in the presence of an S-hydroxynitrile lyase in a diluent and isolating the cyanohydrin formed from the reaction mixture.
