Abstract
The reaction of 7-carbamoyl- and 7-cyano-6-chloro-5-azaindolines with hydrazine leads to the formation of pyrrolo[2,3-d]pyrazolo[5,4-b]pyridine, whereas the reaction of 7-carbamoyl-5-azaindolines with dimethylformamide diethylacetal gives pyrrolo[1,2-c]pyrido]4,3-d]pyrimidines — two new heterocyclic systems. The chemical properties of the synthesized compounds, including cleavage of the pyrimidine ring under the influence of nucleophilic agents, were studied.
