A Cu-catalyzed synthesis of indoloquinoxalin-6-one has been developed that starts from o-indolyl-N,N-dialkylamines through sp3 C–H bond oxidation α to the nitrogen atom with di-tert-butyl peroxide as oxidant. Other heterocycles, such as pyrrole, imidazole and benzimidazole derivatives also reacted successfully to give their respective fused quinoxalin-6-one derivatives. In this process, one of the
已经开发了一种 Cu 催化合成吲哚喹喔啉-6-one,该合成从邻吲哚基-N,N-二烷基胺开始,通过 sp3 C-H 键将 α 氧化为氮原子,并使用二叔丁基过氧化物作为氧化剂。其他杂环,如吡咯、咪唑和苯并咪唑衍生物也成功地反应得到它们各自的稠合喹喔啉-6-one衍生物。在这个过程中,甲基之一转化为羰基。
