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