在可见光照射下，以荧光素、4 '，5'-二溴荧光素和曙红Y为催化剂，研究了光酸催化三氯乙酰亚胺酯与醇的O-糖基化反应。该方法操作简单，无需中和，在室温下进行。
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.
