Via an imine-protection strategy, we herein present an unprecedented copper-catalyzed oxidative multicomponent annulation reaction for direct synthesis of quinazolinones. The construction of various products is achieved via formation of three C–N and one C–C bonds in conjunction with the benzylic functionalization. The merits of easily available feedstocks, naturally abundant catalyst, good functional
通过亚胺保护策略,我们在这里提出了一种空前的铜催化的氧化多组分环合反应,用于直接合成喹唑啉酮。通过形成三个C–N和一个C–C键以及苄基官能团,可以实现各种产物的构建。易于获得的原料,天然丰富的催化剂,良好的官能团和底物相容性以及作为副产物释放H 2 O的优点,使已开发的化学方法成为获取喹唑啉酮的实用方法。
