Abstract
A photoacid catalyzed O-glycosylation of alcohols with glycosyl trichloroacetimidates in the presence of commercially available phenolic photoacids, fluorescein, 4',5'-dibromo-fluorescein, and eosin Y under visible light irradiation by blue LEDs was developed. The method is operationally simple without neutralization and proceeds at room temperature.
