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。
6-Substituted Indolo[1,2-<i>c</i>]quinazolines as New Antimicrobial Agents
A series of 2‐o‐arylidineaminophenylindoles and their cyclic derivatives (indolo[1,2‐c]quinazolines) were synthesized. The reactions occurred under relatively mild conditions and afforded the desired product in good yields. Molecular structures of the synthesized compounds were confirmed by IR, 1H‐NMR, 13C‐NMR, MS spectra, and elemental analyses. Furthermore, all the final products were screened for
