3-acyl- and 3-alkoxycarbonyl-5-oxo-1,4-dihydroindeno[1,2-b]pyridines, 3,5-acyl- and 3,5-alkoxycarbonyl-1,4-dihydropyridines, pyrazole derivatives, fission of heterocycle with hydrazine

Abstract

The interaction of 3,5-carbonyl-substituted derivatives of 1,4-dihydropyridine and some analogs of it with hydrazine hydrate occurs with fission of the heterocycle. In the case of alkoxycarbonyl-substituted compounds a reverse Michael reaction predominates leading to fragmentation of the molecules.
