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.
由4,6-二甲氧基吲哚(14)制备的N-芳基-4,6-二甲氧基吲哚(15–21)被乙酸钯在乙酸中的转化为吡咯并菲蒽酮(22–28),产率适中(30–65) %)。这些产物与一些缺少甲氧基的吡咯并菲蒽酮生物碱有关。N-苄基吲哚的类似的芳基-芳基偶联反应不能进行。
