This review highlights methods for the synthesis of five-and six-membered heterocycles and
their annulated analogues. These methods are based on anionic domino reactions that …

One-pot synthesis of isoindole fused quinazolin 4-ones via intramolecular 1, 3 hydride
transfer in the presence of acid catalyst has been described. Substrate scope and …

The reaction of (Z)-2-amino-N '-arylbenzamidines with both 2, 3-dichloro-5, 6-dicyano-1, 4-
benzoquinone and 2, 3, 5, 6-tetrachloro-1, 4-benzoquinone have been studied. The …

The formation of metal complexes with acid hydrazides plays an important role in the growth
of their biological activity. A simple synthetic strategy is described for the synthesis of novel …

The reaction of (Z)-2-cyano-3-mercapto-3-(phenylamino) acrylamide with
teteracyanoethylene and 2-dicyanomethyleneindan-1, 3-dione gave thiazine derivatives …

Reactions of 2-amino-N'-arylbenzamidines with butanedione resulted in the formation of 2-
acetyl-3-aryl-2-methyl-2, 3-dihydroquinazolin-4 (1H)-ones instead of the expected 2-acetyl-4 …

Amino-N′-phenylbenzamidine (1a) reacts with tetracyanoethene (TCNE) to give 2-[2-(2-
aminophenyl)-5-imino-1-phenyl-1H-imidazol-4 (5H)-ylidene] malononitrile (11a), 4 …

Abstract Some 5-substituted 3-aminopyrazoles were used for the synthesis of isoindolo [2, 1-
c] pyrazolo [1, 5-a] quinazoline and pyrazolo [5′, 1′: 2, 3] pyrimido [6, 1-a] isoindol …

Abstract Novel reactions of (Z)-2-amino-N′-arylbenzimidamides (1a, b) are described.
When 1a, b are reacted with diphenic, phthalic and succinic anhydrides, in dry ethyl alcohol …

The Thesis begins with a brief introduction (Chapter 1) on heterocyclic chemistry, which then
focuses on nitrogen heteroaromatics and the use of amidines in the synthesis of imidazoles …
