  On the stereochemistry of the Baker's Yeast-mediated reduction of regioisomeric unsaturated aldehydes: Examples of enantioselectivity switch promoted by substrate-engineering

  摘要：

  The Baker's Yeast (BY) reduction of (Z)-2-chloromethyl-3-arylacrylaldehydes was found to afford (R)-2-methyl-3-aryl-propanols showing high enantiomeric excess values. Deuterium incorporation experiments were performed, in order to investigate the mechanism of the bioreduction: the formation of the corresponding substituted 2-benzylacrylaldehydes. as intermediates to be effectively reduced by Baker's Yeast, was suggested. These intermediates were synthesized and submitted to BY reduction to afford the corresponding saturated (R)-alcohols, thus confirming the conclusions drawn from labelling experiments. The enantioselectivity of their bioreduction was found to be opposite with respect to that observed for the corresponding regioisomeric 2-methylcinnamaldehydes. The preparation of the two enantiomers of 2-methyl-3-aryl-propanols by fermentation of two regioisomers represents an interesting example of substrate-controlled enantioselective reaction.

In this study, chiral primary amines are shown to catalyze the asymmetric epoxidation of α-substituted acroleins, a versatile type of 1,1-disubstituted terminal alkene. Among various chiral primary amines explored, the chiral primary-tertiary vicinal diamine derived from trans-1,2-diphenylethane-1,2-diamine is identified as the optimal catalyst, which, in combination

  Enamine protonation: A chiral diamine catalyzes an asymmetric Friedel–Crafts reaction through catalytic enantioselective protonation of an enamine. This process can be applied to a range of α‐substituted acroleins and indoles with high yields of products and high enantioselectivity (up to 94 % ee). An OH/π interaction between H2O and the indole ring was found to play an important role in the transition

  We report, herein, aminocatalytic coupling of α-substituted acrylaldehydes with α-diazoesters, leading to chemoselective C–H insertion or cyclopropanation depending on α-substituents of diazoesters. A chiral primary–secondary diamine catalyst derived from l-tert-leucine enabled the efficient promotion of both C–H insertion and cyclopropanation pathways in good yields and high enantioselectivities at
