摘要:
Herein we report the biocatalytic asymmetric synthesis of cyanohydrins by using a new (R)-HNL from Prunus armeniaca. Several sterically demanding aromatic aldehydes which have never been used as substrates for any known HNLs are employed for the new (R)-HNL from A armeniaca, The cyanohydrins synthesized are obtained in good chemical yield with excellent enantioselectivities.
