Abstract
Reduction of a number of 1-nitro-1-alkenes by fermenting bakers' yeast has been found to be enantioselective, resulting in the formation of optically active 1-nitroalkanes. In most cases, optical purities of the products determined by HPLC analysis of MTPA amides were as high as 83-98% ee. The optimum rate of conversion was obtained when the reaction was carried out at pH 8 and low concentration of substrates. The absolute configuration of ...
