A smooth synthesis of benzo[c][1,5]naphthyridine-6-carbonitrile and benzo[h][1,6]naphthyridine-5-carbonitrile, starting from benzonaphthyridine N-oxides, is achieved by treatment with trimethylsilane carbonitrile (Me3SiCN) in CH2Cl2 at 0–5 °C. The resulting nitriles are then hydrolyzed to the corresponding acids by boiling in aqueous alkali.

Treatment of benzonaphthyridines with chloromethyl phenyl sulfone in the presence of base led to the formation of aziridine rings annelated to the benzonaphthyridine skeleton, whereas their N-oxides underwent vicarious nucleophilic substitution of hydrogen (VNS), thus leading to the corresponding phenylsulfonylmethyl derivatives.
