A simple, clean, and highly efficient green protocol has been developed for synthesis of bis(indolyl), di(bis-indolyl), and tris-indolyl methanes by the reaction of indole with aldehydes and ketones in the presence of oxalic acid dihydrate [(CO(2)H)(2).2H(2)O] and N-cetyl-N, N, N-trimethylammonium bromide (CTAB) in water. Also, tri(bis-indolyl) and tetra(bis-indolyl)methanes as new bis(indolyl)methanes were prepared under thermal conditions.
一种简单、清洁、高效的绿色合成方法已被开发出来,用于在草酸二水合物[(CO(2)H)(2).2H(2)O]和 N-十六烷基-N,N,N-三甲基溴化铵(CTAB)存在下,通过吲哚与醛和酮的反应合成双(吲哚基)、二(双吲哚基)和三吲哚基甲烷。此外,在热条件下还制备了三(双吲哚基)和四(双吲哚基)甲烷作为新型双(吲哚基)甲烷。
