[摘要]:We have developed a simple method for the synthesis of diindolophenazine and dipyrrolophenazine derivatives by the aerobic oxidative coupling of 3-aminocarbazole and 2,3-dimethyl-5aminoindole derivatives, respectively, in the presence of catalytic CuBr (10 mol%) in DMSO at 80 degrees C while open to air. |
