Abstract

The multicomponent coupling reaction of catechol, ammonium acetate, and benzyl alcohol/benzyl methyl ether in the presence of a Fe(III) catalyst precursor afforded benzoxazole derivatives in good to excellent yields. The notable features of this protocol are abundant availability of the catalyst system, large-scale synthesis, high diversity, and high yields of products.

摘要

在铁（III）催化剂前体存在下，邻苯二酚、醋酸铵与苯甲醇/苄基甲基醚的多组分偶联反应以良好至优异的产率得到苯并恶唑衍生物。该方法的显著特点是催化剂体系易于获得、可大规模合成、多样性高且产物产率高。
