groups tethered at the para position of the aromatic ring undergo an intramolecular Fischer indolization reaction to give the corresponding indolophanes. Strategic insertion of a double bond in the tether enables a tandem aromatic [3,3] sigmatropic rearrangement reaction to occur to give tricyclic benzo[cd]indoles.
在系链的末端:具有在芳香环对位栓合的羰基的芳基酰肼经过分子内费歇尔吲哚化反应,得到相应的吲哚烷。在链中策略性地插入双键可使串联芳族[3,3]σ重排反应发生,从而生成三环苯并[ cd ]吲哚。
