Synthesis and spectral characterisation of novel 2,3-disubstituted quinazolin-4(3H)-one derivatives

A new series of 2,3-disubstituted quinazolinones was synthesised via the reaction of readily obtainable 2-thioxo-3-phenylquinazolin-4(3H)-one 1 with ethyl chloroacetate followed by hydrazinolysis to afford the hydrazide 3. This was allowed to react with d

SYNTHESIS AND CHEMISTRY OF 2-(5-MERCAPTO-4-PHENYL-1,2,4-TRIAZOL-3-YL)-3-PHENYL-4(3H)-QUINAZOLONE

Several 4-phenyl-1-(3-phenyl-4(3H)-oxo-2-quinazolinylthioacetyl) thiosemicarbazide (4) and 2-(5-Mercapto-4-phenyl-1,2,4-triazol-3-yl)-3-phenyl-4(3H)-quinazolone (5) have been synthesized by condensation of 3-Phenyl-4(3H)-oxo-2-quinazolinyl-thioacetyl hydr

Synthesis of 5-Mercapto-1,2,4-triazole Derivatives Containing 4(3H)-Quinazolone Nucleus

3-(3,4-Dihydro-4-oxo-3-phenylquinazolin-2-ylmercaptomethyl)-5-mercapto-4-phenyl-1,2,4-triazole (VII) and 3-(3,4-dihydro-4-oxo-3-phenylquinazolin-2-ylmercaptopropyl)-5-mercapto-4-phenyl-1,2,4-triazole (VIII) have been synthesized.S-Alkylation of VII and VIII and the reaction of VIII with N-arylchloroacetamides and N1-chloroacetyl-N2-arylureas have been carried out.
