2-Cyano-4-pyrone obtained from comanic acid ethyl ester reacts with amines and hydrazines with the opening of the pyrone ring and substitution of the cyano group to form carbamoylated aminoenones (yields 62–87%) and pyrazolylacetic acid hydrazides. The reactions of 2-cyano-4-pyrone with hydroxylamine or sodium azide involve exclusively the cyano group, which makes it possible to obtain 2-heteroaryl-4-pyrones

Reactions of 5-nitropyridin-2(1H)-one and its N-methyl derivative with hydrazine hydrate led to the formation of (1H-pyrazol-3-yl)acetohydrazide. Under analogous conditions, 1,3-dimethyl-5-nitropyridin-2(1H-one gave rise to 2-(1H-pyrazol-3-yl)propionohydrazide, while 6-methyl-5-nitropyridin-2(1H-one was converted into (5-methyl-1H-pyrazol-3-yl)acetohydrazide. Hydrazinolysis of4-methyl-5-nitropyridin-2(1H)-one resulted in the formation of 3-methyl-4-nitro-1H-pyrazole. The mechanism of recyclization of nitropyridine derivatives by the action of hydrazine hydrate was studied using 5-nitropyridin-2(1H)-one and 1-methyl-5-nitropyridin-2(1H)-one as examples.
