  Enantioselective Organocatalytic Double Michael Addition Reactions

  摘要：

  [GRAPHICS]A novel organocatalytic, enantioselective domino double Michael addition reaction of alpha,beta-unsaturated aldehydes with ethyl 4-mercapto-2-butenoate has been developed. The process is promoted by chiral diphenylprolinol TMS ether to give chiral tetrahydrothiophenes in high to excellent levels of enantioselectivities.
