Thiosemicarbazide Derivatives as Building Block in Synthesis of Target Heterocyclic Compounds with Their Antimicrobial Assessment

1-(2-Benzamido-3-(1,3-diphenyl-1H-pyrazol-4-yl)acryloyl)-4-phenylthiosemicarbazide is used as precursor for synthesis of imidazole, 1,3,4-oxadiazole, 1,3,4-thiadiazole, 1,3-oxazine, and 1,2,4-triazine ring systems. The antimicrobial activity of some of th

Synthesis of Novel Heterocycles Derived from 4-Arylmethylene-2-phenyl-1,3-oxazole-5(4H)-ones

The acid hydrazide derivatives 2 were converted into pyrazolone, triazinone, and schiff bases. However, the reaction of Schiff base 12 with malononitrile or thioglycolic acid gives the pyrazolotriazinone or thiazolidinone derivative, respectively. The str

Action of Some Nitrogen and Carbon Nucleophils on 4-Arylidene-1,3-oxazolones

(Chemical Equation Presented) 1,3-Oxazolones 1 and 2 were reacted with hydrazine hydrate to afford the corresponding hydrazides 3 and 4. Treatment of the hydrazides withacetylacetone, acetonylacetone, ethyl acetoacetate and diethyl malonateyielded different heterocycles. However, oxazolones 1 and 2 reacted with methyl p-aminobenzoate to afford the imidazolones 5a,b which were converted into the hydrazide 3a or the triazinone derivative 6 upon treating with hydrazine hydrate. The structures of the newly synthesized compounds were established using IR, 1H-NMR, EIMS, and elemental analyses.

A convenient synthesis of some novel pyrazole derivatives

A range of some novel pyrazole derivatives has been prepared in moderate to good yield by the reaction of 3-aryl-1-phenyl-1H-pyrazole-4-carbaldehydes 1a,b as a starting material with some reagents such as acylglycine, benzamidine hydrochloride, malononitr
