The synthesis of some dibenzo[b,f]-[1,8]naphthyridine derivatives in a cascade manner is reported. The reaction includes a Knovenagel condensation, the insertion of a nitrile and an alkyne into an N–H bond and an oxidation/oxidative C–C bond cleavage sequence in the presence of copper iodide. The key 1,8-naphthyridine core was constructed in a cascade manner during the course of the reaction itself which allows diverse dibenzo[b,f]-[1,8]naphthyridine derivatives to be readily prepared. (Figure presented.).
