A simple, efficient and practical approach to 1H-indolo[1,2-c]quinazolinederivatives has been developed that uses inexpensive and readily-available catalyst and substrates. The method should provide a new strategy for N-fused heterocycles and will show wide application in organic chemistry and medicinal chemistry.

An efficient synthesis of indolo[1,2-c]quinazolinederivatives has been developed by copper-catalyzed sequential Ullmann N-arylation and aerobic oxidative C–H amination. The protocol uses readily available 2-(2-halophenyl)-1H-indoles and (aryl)methanamines as the starting materials to afford indolo[1,2-c]quinazolines, which are the core units of hinckdentine A.
通过铜催化的顺序Ullmann N-芳基化反应和好氧氧化CH-H胺化反应,已开发出吲哚[1,2- c ]喹唑啉衍生物的有效合成方法。该协议使用容易获得的2-(2-卤代苯基)-1 H-吲哚和(芳基)甲胺作为起始原料来提供吲哚并[1,2- c ]喹唑啉,它们是hinckdentine A的核心单元。
