摘要
Unprotected thioglycosides were effective nucleophiles for Ni-0-catalyzed CS bond-forming reaction with functionalized (hetero)aryl, alkenyl, and alkynyl halides. The functional-group tolerance on the electrophilic partner was typically high and the anomeric selectivities of the thioglycosides were high in all cases. The efficiency of this general procedure was well-demonstrated by the synthesis of 4-methyl-7-thioumbelliferyl--D-cellobioside (MUS-CB).
