Wang, Meng published the artcileCopper-catalyzed N-arylation and aerobic oxidative C-H/C-H coupling: one-pot synthesis of indoloimidazoquinoline derivatives, Recommanded Product: 5,6-Dimethoxy-1H-benzo[d]imidazole, the main research area is copper arylation aerobic oxidation coupling indoloimidazoquinoline preparation; benzimidazoindoloquinoline preparation.
A novel and efficient copper-catalyzed one-pot synthesis of indoloimidazoquinoline derivatives has been developed. The synthesis of the target compounds was achieved by a protocol using readily available substituted 2-(2-bromophenyl)-1H-indole derivatives, imidazole and benzimidazole derivatives as starting materials, inexpensive copper bromide (CuBr) as a catalyst, air as a terminal oxidant. The procedure underwent a sequential copper-catalyzed intermol. N-arylation and an aerobic oxidative intramol. C-H/C-H coupling. The title compounds thus formed included a heterocyclic compound (I) [i.e., 5H-benzimidazo[1,2-a]indolo[3,2-c]quinoline] and related substances, such as 9H-imidazo[1,2-a]indolo[3,2-c]quinoline.
RSC Advances published new progress about Arylation. 72721-02-9 belongs to class imidazoles-derivatives, name is 5,6-Dimethoxy-1H-benzo[d]imidazole, and the molecular formula is C9H10N2O2, Recommanded Product: 5,6-Dimethoxy-1H-benzo[d]imidazole.
