Substituent effects on the stereochemical outcome of the baker’s yeast-mediated biotransformation of α-hydroxy- and α-acetoxymethyl-5-phenylfuran-2-yl-ethanones
摘要:
In this Letter the baker's yeast-mediated biotransformation of variously substituted alpha-hydroxy- and alpha-acetoxymethyl-5-phenylfuran-2-yl-ethanones is described. The stereochemical outcome of the reactions was strongly influenced by the nature of the substituents on the phenyl ring. (C) 2010 Elsevier Ltd. All rights reserved.

Abstract Baker'syeastmediated reduction of various phenylfuran-2-yl-ethanones has been studied. The influence of the reaction conditions, the type and position of the substituents, as well the presence of various additives on the enantiomeric composition of the products and the reaction yield are discussed. The absolute configuration of the reaction products was established using a retrosynthetic
