Enantioselective synthesis of α-hydroxysilanes by bioreduction of aroyltrimethylsilanes
Abstract
Aromatic acylsilanes [Ar-CO-SiMe3; Ar = C6H5, 4-ClC6H4, 2-, 3- and 4-OMeC6H4, 3,4-(OMe)2C6H3 and 3,4-OCH2OC6H3] were reduced by baker’s yeast to optically active α-silyl alcohols in 20–70% yield and 43–88% ee. Comments are made on the influence of silicon in this bioreduction reaction.
