A NOVEL SYNTHESIS OF 2,2'-BISINDOLE AND ITS APPLICATION FOR THE SYNTHESIS OF INDOLO[2,3-A]CARBAZOLE DERIVATIVES

A novel oxidative coupling method of 2-lithio-1-methoxyindole was developed resulting in the formation of 2,2'-bis(l-methoxyindole) (6). Catalytic hydrogenation of 6 produced 2,2'-bisindole (9). Diels-Alder reaction of 9 with dienophiles afforded indolo-[2,3-a]carbazole derivatives.
