4,6-dimethoxyindole (14), were converted by palladium acetate in acetic acid into the pyrrolophenanthridones (22–28) in moderate yields (30–65%). These products are related to some pyrrolophenanthridone alkaloids, which lack the methoxyl groups. Similar aryl-aryl coupling reactions of N-benzylindoles could not be effected.
