Asymmetric synthesis of SM-9164, a biologically active enantiomer of antifungal agent SM-8668

SM-9164, a biologically active enantiomer of antifungal agent SM-8668, was prepared by asymmetric synthesis in 10 steps in 13% overall yield from commercially available 2-chloro-1-(2,4-difluorophenyl)ethanone. The crucial steps were Katsuki-Sharpless asymmetric epoxidation of the (E)-allylic alcohol and epimerization of the erythro-sulfone to the desired threo-isomer under basic conditions.
