An electrochemically oxidative domino cyclization reaction of methyl azaarenes/ketones with pyrazol-5-amines and 6-amino-pyrimidine-2,4-diones was developed, providing a variety of dipyrazolo[3,4-b:4′,3′-e]pyridines and dipyrimidine-fused pyridines with moderate to good yields. The reaction involved two C–C bond formations and one C–N bond formation in one pot. Moreover, the photoluminescence properties of the representative dipyrazolo[3,4-b:4′,3′-e]pyridines were investigated.
