  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.

  旧的黄色酶1-3生物催化还原活化的四取代烯烃的立体化学结果。

  摘要：

  四取代活化烯烃的（E）和（Z）立体异构体的烯还原酶介导的反应是通过分离的旧黄色酶（OYEs）1-3进行的。对所得数据的理解需要仔细分析这种反应的立体化学过程。对四取代烯烃的生物还原的研究使我们认识到几个因素（起始烯烃的构型，氢加成的机理，底物结合模式）对反应的整体立体化学的贡献。

  quantitatively in situ, in THF−H2O at pH 7, by addition of AuBr3 (but not with other MXn!). Adducts arising from asymmetric nitro-Michael and nitro-aldol reactions afford 1,4-diketones and α-alkoxy ketones, respectively, with full retention of the configuration of the stereocenters α to the CHNO2/C═N−SPh/C═O groups.

  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
