✦ Synopsis

By employing a vigorously stirred two phase system aqueous buffer/organic solvent and using the hydroxynitrile iyase from Hevea brasii#ensis as biocatalyst enantiopure (S)-cyanohydrins from aliphatic, unsaturated, aromatic and heteroaromatic aldehydes and methyl alkyi and methyl phenyl ketones are obtained in high yield and in general 98-99% enantiomeric excess~
