title: The study of reactions of 7-substituted 8-hydrazino-3-methylxanthine with β-dicarbonyl compounds
abstract: The problem of searching biologically active compounds amidst xanthine derivatives is a crucial one and is an issue for long-term investigation.The aim of this paper was to study reactions of 7-substituted 8-hydrazino-3methylxanthine with acetylacetone and acetoacetic ether.Methods and results. Reaction of 7-substituted 8-hydrazinoxanthines together with acetylacetone is performed by way of forming the respective 7-substituted 8-(3,4-dimethylpyrazole-1-yl)-3-methylxanthines.Interaction of hydraz
