Amberlyst 15 as a mild and effective activator for the glycosylation with disarmed glycosyl trichloroacetimidate donors

Amberlyst 15 acidic resin has been shown to be a mild and effective activator for the glycosylation with commonly used disarmed glycosyl trichloroacetimidate donors. Glucosylation, galactosylation, rhamnosylation, and lactosylation of a panel of representative alcohol and thiol acceptors promoted by Amberlyst 15 allowed for the formation of structurally diverse O- or S-linked oligosaccharides and glycosylated amino acids in moderate to excellent yields.
