Аннотация: New polyfunctional hydrogenated pyrazolo[3,4-b]pyridines were obtained by the chemoselective reaction between N-arylitaconimides and 5-aminopyrazoles. The transformation is the cascade reaction including Michael addition at the active double bond of the itaconimide followed by the intramolecular transamidation and recyclization.

Ключевые слова: pyrazolo[3,4-b]pyridines, itaconimides, 5-aminopyrazoles, recyclization, chemoselectivity, heterocyclization.
