Abstract

Reactions of 3,5-diamino-4-nitropyrazole with asymmetric β-dicarbonyl compounds formed pyrazolo[1,5-a]pyrimidines, which in turn were used as the starting compounds in the reaction with dimethylformamide diethylacetal. The structure of the compounds obtained was studied by NMR spectroscopy in experiments involving the homonuclear Overhauser effect.
