Biphenyl-4,4'-diyl)bis(hydrazinium) chloride and 2,2'-(naphthalene-1,5-diyl)bis (hydrazinium) chloride were converted via Fischer syntheses with 3-methylbutan-2-one into bisindolenines, 2,2',3,3,3',3'-hexamethyl-3H,3'H-5,5'-biindole 10 and 2,3,3,7,8,8-hexamethyl- 3H,8H-indolo(7,6-g)indole 14, respectively. Exposure of the bisindolenines to the Vilsmeier reagent produced tetraformyl compounds 11 and
联苯-4,4'-二基)双(肼)氯化物和 2,2'-(萘-1,5-二基)双(肼)氯化物通过 Fischer 合成与 3-methylbutan-2-one 转化为双吲哚啉, 2,2',3,3,3',3'-六甲基-3H,3'H-5,5'-二吲哚10和2,3,3,7,8,8-六甲基-3H,8H-吲哚(7,6-g) 吲哚 14,分别。双吲哚啉暴露于 Vilsmeier 试剂产生四甲酰基化合物 11 和 15,它们与肼和芳基肼反应,以极好的收率得到相应的吡唑 12 和 16。
