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

Oxidation of 2-furylaninlies with m-CPBA followed by treatment with a base provides access to functionalized indolin-3-ones. The designed oxidativetransformation utilizes an underassessed chemical behavior of furyl-containing amines to form a C–N bond via engaging a β-carbon atom of the furan core upon a ring-forming step, thereby providing an alternative disconnection toward nitrogen-containing heterocycles

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.
