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.
开发了一种在可见光照射下，通过使用商用酚类光酸、荧光素、4',5'-二溴荧光素和曙红 Y 作为光催化剂，在商业上可获得的 photoacid 存在下，用糖基三氯乙酰亚胺酯对醇进行 O-糖基化的反应。该方法操作简单，无需中和，在室温下进行。
