Although trimethylsilyl triflate (TMSOTf) has been widely used to promote glycosyl trichloroacetimidates in oligosaccharide synthesis, silver triflate (AgOTf) was proved to be a mild and in some cases more efficient catalyst in TMSOTf-sensitive glycosylations. Migration and degradation in some specific coupling reactions can be reduced significantly under this alternative glycosylation condition.
