The Complex Reaction of Acetohydrazides with Unsaturated Diketones: Alternative Cyclizations to 1,2-Diazepin-3-ones and Pyrazolopyridines

The reaction of 2-cyanoacetohydrazide (1) and 2-(ethoxycarbonyl)acetohydrazide (26) with unsaturated 1,3-diketones leading with moderate yields to 1,2-diazepinones (3, 23, 24) and pyrazolopyridines (5, 15, 20, 25) together with the corresponding acetohydrazones have been studied.The reaction course depends on the temperature and the relative reactivity of the carbonyl groups of the starting materials.When one of these carbonyl groups is less reactive (benzoyl or ethoxycarbonyl groups), the reaction does not yield diazepinones but only pyrazolopyridines and/or acetohydrazones.
