Abstract

In the reaction of N′-cyclohexenecarbonyl-substituted hydrazides  of 2-aminobenzoic acid with the trialkyl esters of formic, acetic, valeric, and  benzoic acids at room temperature  3-cyclohexenyl-amidoquinazolin-4-ones with the respective substituent at the C-2 atom of the  quinazoline  ring  were obtained. The spatial structure of the obtained compounds was studied by homonuclear and heteronuclear NMR.
