Microwave-assisted synthesis of polyheterocyclic-fused quinoline-2-thiones through the
annulation of ortho-heteroaryl anilines and CS2 was realized in water without using any …

Tetraphosphorus decasulfide (P4S10) in pyridine has been used as a thionating agent for a
long period of time. The moisture-sensitive reagent has now been isolated in crystalline …

Phosphazo compounds containing a nitrogen-phosphorus double bond (phospha-h5-
azenes) are called iminophosphoranes and were tirst prepared via the reaction of tehary …

An efficient method for the synthesis of nitrogen heterocycles containing a cyclic amidine

Reflux of equimolecular amounts 2-aminobenzylamine and isatins in acetic acid produced
indolo [3, 2-c] quinolin-6-ones in good yields. A proposed mechanism involving initial …

A series of 6-arylbenzothieno [3, 2-c] quinolines were synthesised in three steps from benzo
[b] thiophene. After a selective Heck-type coupling of benzo [b] thiophene with different o …

A three-step synthesis of indoloquinoline alkaloids is described. The reaction of 2, 3 and 4-
substituted haloquinolines with anilines afforded the respective anilinoquinolines, which …
