Some new substituted 1,8- naphthyridines 2a, 2b, 2c, 2d, 2e, 2f, 2g have been synthesized by treating various 2-substituted vinamidinium salts 1a, 1b, 1c, 1d, 1e, 1f, 1g with 2,6-diaminopyridine. The structures of the synthesized compounds have been established on the basis of elemental analysis and spectroscopic data (H-1-NMR, C-13-NMR, IR, UV/VIS, and mass).
