The utility of 4-isothiocyanato-N-(1-phenyl-1 H-pyrazol-5-yl) benzene sulfonamide 2 in the
synthesis of some novel thiosemicarbazide, carbamothioate, 1, 3, 4-thiadiazole, azomethine …

The novel thiosemicarbazide derivative was prepared by hydrazinolysis of
isothiocyanatosulfonamide with hydrazine hydrate. It was used as a starting material for the …

Abstract N-(4-(Pyrazol-4-yl) thiazol-2-yl)-N′-phenylthiourea derivative 2 was synthesized
and then treated with variety of hydrazonoyl chlorides under basic condition at reflux to …

Objective: This study aimed synthesis of benzothiazole and thiazole derivatives due to the
importance of these heterocycles as anticancer. Method: Novel benzothiazole and thiazole …

Many novel thiazole derivatives were designed and synthesized using 4-phenylthiazol-2-
amine. The reactivity of the latter compound toward different chemical reagents was studied …

Methyl-1H-pyrazol-5 (4H)-one (1) was used as a template to develop new anticancer
compounds and investigate their SAR. The ring modification of compound 1 occurred …

Substituted aromatic amines were diazotized followed by coupling with malononitrile to
afford substituted phenyl hydrazono-malononitrile compounds 2a-c. Compounds 3a-c were …

A novel series of 2-ethylidenehydrazono-5-arylazothiazoles 5a-h and 2-
