title: Stereoretentive Copper-Catalyzed Directed Thioglycosylation of C(sp2)-H Bonds of Benzamides.
abstract: An efficient thioglycosylation of C(sp2)-H bonds with thiosugars has been established for the first time. Using only Cu(OAc)2⋅H2O as a catalyst and Ag2CO3as an additive in DMSO, the protocol proved to have broad scope, and a variety of complex thioglycosides have been prepared in good yields with exclusive β-selectivity.
