Abstract

Reactions of 2-R-6,8-dinitro[1,2,4]triazolo[1,5-a]pyridines with indoles and 1,3-dicarbonyl compounds were studied. It was found that stable products of nucleophilic addition to the pyridine ring were formed under mild conditions in the absence of a base. The new derivatives of 1,5-dihydro[1,2,4]triazolo[1,5-a]pyridine were synthesized in up to 96% yield.
