以水作溶剂在三乙基苄基氯化铵(TEBA)存在下,取代肉桂腈与β-萘酚发生 加成缩合反应,通过简单的抽滤即可得到萘并吡喃衍生物,与其他的方法相比该方 法具有产率高、价廉、环境友好等优点。

关键词: 肉桂腈, 萘酚, 三乙基苄基氯化铵, 缩合反应

The reactions of substituted cinnamonitriles withβ-naphthol proceed very efficiently in water in the presence of triethylbenzylammonium chloride (TEBA) to give naphthopyran derivatives, which were isolated simply by filtration. Compared to the previous methods, this new method has the advantages of high yields, inexpensive medium and environmentally friendly processes.

Key words: cinnamonitrile, NAPHTHALENOL, TEBA, CONDENSATION REACTION
