  Enantioselective Organocatalytic Oxidation of Functionalized Sterically Hindered Disulfides

  摘要：

  The first study on enantioselective oxidation of functionalized sterically hindered disulfides is reported. This study shows that the Shi organocatalytic system using carbohydrate-derived ketone with oxone is superior to the Ellman-Bolm vanadium catalyst in terms of chemical yield and enantioselectivity. Whereas the latter system afforded mostly racemic thiosulfinates in low to moderate yields, the former one afforded thiosulfinates with up to 96% ee.
