title: Thioperoxide-mediated activation of thioglycoside donors.
abstract: Thioperoxide (1) in combination with trimethylsilyl trifluoromethanesulfonate (TMSOTf) provides a powerful thiophilic promoter system, capable of activating different thioglycosides. Both armed and disarmed thioglycosides were activated effectively in the presence of different glycosyl acceptors, giving glycosidation products in high to excellent yields. A plausible activation pathway was also proposed and supported by isolating side-products trifluoromethylphenyl disulfide (CF3SSPh) and alkene (42).
