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

Arylquinoline derivatives and their use for treating cancer or cancer metastasis is disclosed. The compounds of the subject technology promote cells to secrete a pro-apoptotic tumor suppressor, i.e., prostate apoptosis response-4 (Par-4), which in turn promote apoptosis in cancer cells or metastatic cells.

Condensation of 2-(cyanomethyl)benzoic acid with 2-aminobenzylamine gave 6,11-dihydro-13H-isoquino[3,2-b]quinazolin-11-one. Its oxidation in nitrobenzene led to the formation of 5,13,5',13'-hexahydro[6,6']bi[isoquino[3,2-b]quinazoline]-11,11'-dione, but in dichlorobenzene in the presence of elemental sulfur and iodine it gave the rearrangement product 6H-dibenzo[b,f][1,8]naphthyridin-5-one.
