A novel C~-symmetric bis-sulfoxide 1 was synthesized as a chiral auxiliary for asymmetric desymmetrization of meso-1,2-diols. cis-Cyclohexane-1,2-dioi and cis-cyclopentane-1,2-diol were desymmetrized via acetalization with I followed by basepromoted acetal cleavage with high diastereoselectivity (>9

Desymmetrization reactions of meso compounds through enantioselective catalysis are a powerful strategy for the synthesis of chiral molecules with multiple stereocenters. One well-known example is the Pd-catalyzed desymmetrization of meso-2-alkene-1,4-diol derivatives (Trosts Pd-catalyzed asymmetric
