文摘

This work describes the utility of a catalyst system (AuCl3-AgOTf) for O-glycosylation at room temperature. This has been discovered after screening different combinations of catalysts. Both armed and disarmed glycosyl sulfoxides readily lead to the corresponding O-glycosides at room temperature within 25–60 min. We are sure this method will be useful in carbohydrate chemistry.
