Abstract
Abstract Phtalic acid derivative of o-methylcarboxybenzoylchloride readily acylates N(1-cyclohexenyl) morpholine and is likely to acylate other enamines along the classic path to 1,3-diketones. It is a convenient route towards o-(1-(1,3-diketone)) derivatives of benzoic acid, which are precursors of o-(heteroaryl)-benzoic acids. Further conversions with hydrazines and amidines lead to pyrazolo[ [5] , [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] ]isoindole and pyrimidine rings respectively. The structures of the obtained compounds were confirmed by X-ray structure determinations.
