afforded (R)- or (S)-β-hydroxy nitriles with excellent optical purity and yield. Subsequently, nitrilase-catalyzedhydrolysis of the obtained optically pure β-hydroxy nitriles led to the corresponding β-hydroxy carboxylic acids in high yields. More importantly, the sequential enzymatic reduction and hydrolysis could be carried out in “two-step-one-pot” fashion without the isolation of intermediates β-hydroxy
