Novel synthetic methods for the production of butyl (S)-2-hydroxybutanoate starting from butyl (2S,3R)-epoxybutanoate or butyl (S)-2,3-epoxypropanoate were established. The former method utilized the regioselective thiolysis of the epoxybutanoate mediated by scandium triflate and subsequent reductive cleavage of the thioether to give butyl (S)-2-hydroxybutanoate with stereochemical retention in quantitative yield. The latter method utilized one-step conversion by a combination of methylmagnesium bromide and copper catalyst in high yield. Georg Thieme Verlag Stuttgart, New York.
