摘要:
Process for preparing (S)-cyanohydrins by reacting aldehydes or asymmetrical, aliphatic ketones with hydrocyanic acid in the presence of the (S)-oxynitrilase from Hevea brasiliensis at temperatures of up to at most 10.degree. C.
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.
