3-苯基-2-硫代-2,3-二氢-4(1H)-喹唑啉酮 | 3-phenyl-2-thioxo-2,3-dihydro-1H-quinazolin-4-one | 18741-24-7 | C14H10N2OS | 254.312 |
A new series of 2,3-disubstituted quinazolinones was synthesised via the reaction of readily obtainable 2-thioxo-3-phenylquinazolin-4(3 H)-one 1 with ethyl chloroacetate followed by hydrazinolysis to afford the hydrazide 3. This was allowed to react with different electrophilic reagents such as carbon disulfide, phenyl isothiocyanate, β-diketones, anhydrides, acrylonitrile, ethyl cinnamate, aldehydes, arylidene malononitrile and lauroyl chloride. Some of the newly synthesised compounds showed promising anti-inflammatory activities.
