One-pot, simple, and facile synthesis of 4-(3-benzylbenzo[d]thiazol-2(3H)-ylidene)-cyclohexa-2,5-dien-1-one derivatives via a novel three-component reaction

Abstract

In this study, a series of 4-(3-benzylbenzo[ d]thiazol-2(3 H)-ylidene)-cyclohexa-2,5-dien-1-one derivatives are efficiently synthesized in excellent yields by reactions of 2-chlorobenzothiazole, benzyl bromides, and phenols in acetonitrile under reflux and catalyst-free conditions in the presence of triethylamine for 2 h. The structures of the products are characterized by NMR, IR, EI-MS, and elemental analyses.
