Tandem synthesis of substituted 2,7-naphthyridin-1(7H)-ones via Reissert reaction/intramolecular nucleophilic addition/oxidation dehydrogenation

A convenient method for the synthesis of substituted 2,7-naphthyridin-1(7H)-ones has been developed. This method was carried out starting from a simple nicotinamide salts via a tandem process including Reissert reaction, intramolecular nucleophilic addition and oxidation dehydrogenation. Using this method, a variety of substituted 2,7-naphthyridin-1(7H)-ones were obtained in good yields.
