用于合成吡唑并[4,3- f ]喹啉,吡唑并[3,4- f ]喹啉和吡唑并[3,2- f ]喹啉衍生物的有效原位还原和环化反应直接形成5-硝基吲唑,据报道在SnCl 2 ·2H 2 O存在下6-硝基吲唑和5-硝基吲哚。与传统的合成方法相比,该方法具有试剂稳定,原料易得,收率高的优点。在本研究中,SnCl 2 ·2H 2 O是硝基化合物原位还原和环化反应的有效还原剂。此外,该方法为合成目标化合物提供了另一种方法。

A combinatorial synthesis of pyrrolo[3,2-f]quinoline and pyrrolo[3,2-a]acridinederivatives is described as a three-component reaction of aromatic aldehyde, 1H-indol-5-amine, and 1,3-dicarbonyl compounds undercatalyst-freeconditions. The 1,3-dicarbonyl compounds include 5,5-dimethylcyclohexane-1,3-dione, cyclopentane-1,3-dione, and 2H-indene-1,3-dione. It is interesting that the designed reactions
