nitro-derivatives (4a–c) with iron–acetic acid leads to the pyrrolo[3,2-b]indoles (7a–c). This unusual indolization, in which displacement of the heterocycle amino-group occurs, is regarded as a nucleophilic attack by the 2-aminophenyl group on the pyrrole ring, and is an interesting example of intramolecular nucleophilic substitution in the pyrrole series.
用铁-乙酸还原硝基衍生物(4a–c)会导致吡咯并[3,2- b ]吲哚(7a–c)。这种不寻常的吲哚化,其中发生杂环氨基的置换,被认为是吡咯环上的2-氨基苯基的亲核攻击,并且是吡咯系列中分子内亲核取代的有趣例子。
