Abstract

[GRAPHICS]A role of achiral oxazolidinones to enhance the enantioselectivity in reactions of N-cinnamoyloxazolidinones with alkyl radicals promoted by a chiralLewis acid Is described. Efficient enantioselective radical-mediated conjugate additions of N-cinnamoyloxazolidinone can be realized by use of a chiral zinc triflate generated from a readily prepared chiral bisoxazoline and an achiral oxazolidinone. The NH moiety of achiral oxazolidinones is found to be necessary to enhance the enantioselectivity.
