Enantio- and chemoselective bioreduction of β-keto nitriles by the fungus Curvularia lunata
摘要:
The use of methanol as cosolvent allows the chemoselective reduction of aromatic beta -keto nitriles by the fungus Curvularia lunata CECT 2130, yielding the corresponding (S)-beta -hydroxy nitriles in a highly enantioselective way. (C) 2000 Elsevier Science Ltd. All rights reserved.

Rhodococcus erythropolis SET1, a novel nitrilehydrolysing bacterial isolate, has been undertaken with 34 nitriles, 33 chiral and 1 prochiral. These substrates consist primarily of β-hydroxy nitriles with varying alkyl and aryl groups at the β position and containing in several compounds different substituents α to the nitrile. In the case of β-hydroxy nitriles without substitution at the α position

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
