O,O-Dimethylthiophosphonosulfenyl bromide (DMTPSB) in combination with silver triflate provides a powerful thiophilic promotersystem. Both “armed” and “disarmed” thioglycoside glycosyl donors can be activated to form glycosidic linkages efficiently by the pre-activation protocol. The usefulness of this newpromoter is illustrated by a successful iterative one-pot oligosaccharide assembly.
