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
