Hydroxynitrile lyase from the Japanese apricot (Prunus mume) catalyzes the formation of several aliphatic cyanohydrins in an asymmetric fashion. By employing a biphasic reaction system, aliphatic aldehydes with various structural features can be converted to the corresponding (R)-cyanohydrins with good overall yield and enantiomeric excess.

2-Monosubstituted (S)-aziridines (S)-3 were obtained by hydrogenation of (R)-2-sulfonyloxynitriles (R)-2 with LiAlH4 in good chemical yields and high enantiomeric excess.
