The reactions of 4-carbamoyl- and 4-cyanopyridin-3-one and 4-cyanoisoquinolin-3-one with DMFA diethyl acetal were studied, and hydrogenated di- and trimethylene derivatives of 2,7-naphthyridine-1,8-dione were synthesized.It was found that O- or N-alkylation reactions of the pyridone fragment of the starting bicyclic compounds take place together with the condensation of the DMFA acetal at the amide amino group or the active methylene unit.
