Abstract: Asymmetric desymmetrization of meso-vic-diols was achieved by carbamoylation in the presence of copper triflate and (S,S)-Ph-BOX as a catalyst without any use of bases. The method was successfully applied to asymmetric desymmetrization of five- to eight-membered cyclic meso-vic-diols in high enantioselectivity with up to 93% ee.
