Quinazolinones have broad applications in the biological, pharmaceutical and material fields. Studies on the synthesis of these compounds are therefore widely conducted. Herein, a novel and highly efficient copper-mediated tandem C(sp2)–H amination and annulation of benzamides and amidines for the synthesis of quinazolin-4(1H)-ones is proposed. This synthetic route can be useful for the construction of quinazolin-4(1H)-one
喹唑啉酮类在生物学,制药和材料领域具有广泛的应用。因此,对这些化合物的合成进行了广泛的研究。在此,提出了一种新颖且高效的铜介导的串联C(sp 2)-H胺化和苯甲酰胺和am的环化反应,以合成喹唑啉-4(1 H)-一。该合成路线可用于构建quinazolin-4(1 H)-one框架。
