Synthesis and stereochemical structure of derivatives of 2-substituted 3-cyclohexenylamidoquinazolin-4-ones obtained from N′-cyclohexenecarbonyl-substituted hydrazides of 2-aminobenzoic acid and certain orthoesters
摘要:
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-cyclohexenylamidoquinazolin-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.
