Microbial Asymmetric Oxidation of 2-Alkoxyethylsulfides and a Facile Synthesis of Chiral Vinyl Sulfoxide

Abstract
2-Alkoxyethyl phenyl sulfides were oxidized by incubation with Rhodococcus equi IFO 3730 to afford chiral sulfoxides of high enantio excess. Phenyl vinyl sulfoxide and 2-hydroxyethyl phenyl sulfoxide were obtained from microbial oxidation products without any loss of their optical purities.
