Synthesis of N′-cyclohexenecarbonyl-substituted hydrazides of 2-aminobenzoic acids and preparation of 3-cyclohexenyl-amido-1,2-dihydroquinazolin-4-ones based on them

N′-Cyclohexenecarbonyl-substituted hydrazides of 2-aminobenzoic acids were obtained from the reaction of isatoic anhydride with monohydrazides of cyclohexenedicarboxylic acid. Reaction of the 2-aminobenzoic acid hydrazides with substituted benzaldehydes gave 3-cyclohexenylamido-1,2-dihydroquinazolin-4-ones. __________ Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 6, 894–898, June, 2007.
