  Hydroxynitrile lyase catalyzed enantioselective HCN addition to O-protected α-hydroxyaldehydes

  摘要：

  Various O-protected glycol- and racemic lactaldehydes 3 and 6 as well as O-allyl protected racemic alpha-hydroxyaldehydes 7 (R-1=Et Pr, Bu) have been prepared to investigate and perform a stereoselective Kiliani-Fischer synthesis by hydroxynitrile lyase (HNL) catalyzed addition of HCN. From all protecting groups investigated the allyl moiety was most suitable. (R)-PaHNL from bitter almonds (Prunus amygdalus), yielding the (2S)-cyanohydrins 8-10, was found to be a more stereoselective catalyst than (S)-MeHNL from maniok (Manihot esculenta). While (R)-PaHNL led to enantiomeric excesses greater than or equal to 93%, with (S)-MeHNL the (2R)-cyanohydrins 8-10 were obtained with enantiomeric excesses less than or equal to 78%.
