The reaction of 2-aryl-5-acetoxy-4,8-di-tert-butyl-2H-naphtho[1,8-bc]furan with dichloromethyl ethyl ether in the presence of aluminum chloride gave rise to 6-formyl derivatives of the title heterocyclic system, and at the use of aliphatic acids anhydrides in the presence of perchloric acid 6-acyl derivatives were obtained. The target products with a peri-hydroxycarbonyl group were obtained by the ester group elimination.
在氯化铝存在下,2-芳基-5-乙酰氧基-4,8-二叔丁基-2H-萘并[1,8-bc]呋喃与二氯甲基乙醚反应生成了标题杂环体系的 6-甲酰基衍生物,而在高氯酸存在下使用脂肪族酸酐则可得到 6-酰基衍生物。通过酯基消除,可以得到带有过羟基羰基的目标产物。
