Abstract

We have developed a general and highly efficient copper-catalyzed method for synthesis of quinazoline and quinazolinone derivatives, the target products were obtained in good to excellent yields via cascade reactions of amidine hydrochlorides with substituted 2-halobenzaldehydes, 2-halophenylketones, or methyl 2-halobenzoates, and the method is of simple, economical and practical advantages.
