  Copper complex catalyzed asymmetric monosulfonylation of meso-vic-diols

  摘要：

  A symmetric desymmetrization of meso-vic-diols was performed by tosylation in the presence of copper(II) triflate and (R,R)-Ph-BOX as a catalyst. The method was successfully applied to asymmetric desymmetrization of cyclic and acyclic meso-vic-diols in high enantioselectivity with up to >99% ee. (C) 2007 Elsevier Ltd. All rights reserved.

  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. (c) 2006 Elsevier Ltd.
