The reaction of 2-acetyl-5,6,7,8-tetrahydronaphthalene 1 with some aldehydes was conducted in the presence of ethyl cyanoacetate and ammonium acetate, yielded the cyanopyridones 2a-c, which react with phosphorous pentasulphide to afford the corresponding thioxopyridine derivatives 3a-c,
Acetic acid ethyl esters containing 5-oxo-[1,2,4]triazole ring (2) were synthesized by the condensation of compounds 1a-f with ethyl bromoacetate in basic media. The reaction of compounds 2a-f with hydrazine hydrate led to the formation of acid hydrazides (3a-f). The treatment of compounds 3 with
