Asymmetric reduction of nitroalkenes with baker's yeast
摘要:
Various alpha,beta -disubstituted and trisubstituted nitroalkenes were chemoselectively reduced with baker's yeast to the corresponding nitroalkanes. Stereoselectivities of the reduction of alpha,beta -disubstituted nitroalkenes were modest to low, and e.e.s up to 52% were obtained. Trisubstituted nitroalkenes could be reduced to the corresponding nitroalkanes with excellent enantioselectivities, moderate diastereoselectivities and in good yield. (C) 2001 Elsevier Science Ltd.

old yellow enzymes (OYEs) 1–3. The comprehension of the resulting data required a careful analysis of the stereochemical course of this kind of reaction. The investigation of the bioreduction of tetrasubstituted alkenes allowed us to appreciate the contribution of several factors (configuration of the starting alkene, mechanism of hydrogen addition, substrate binding mode) to the overall stereochemistry
Two kinds of novel nitroalkene reductases were isolated from baker'syeast. Reduction of a trisubstituted nitroalkene by these reductases afforded the corresponding nitroalkane with excellent enantioselectivity, moderate diastereoselectivity, and in good yield.
