Synthesis of some 3-substituted [1,8]Naphthyrido[3,2-c][1,8]naphthyridines. A new heterocyclic ring system was written by Ferrarini, Pier Luigi;Biagi, Giuliana;Livi, Oreste;Primofiore, Giampaolo;Carpene, Marino. And the article was included in Journal of Heterocyclic Chemistry in 1981.Formula: C7H9N3O This article mentions the following:
The title compounds (I; R = Me, Br, Cl, EtO, HS) were prepared by condensation of naphthyridinones (II) with 2-aminonicotinaldehyde. I were transformed into the fully aromatic compounds by refluxing with nitrobenzene. In the experiment, the researchers used many compounds, for example, N-(6-Aminopyridin-2-yl)acetamide (cas: 1075-62-3Formula: C7H9N3O).
N-(6-Aminopyridin-2-yl)acetamide (cas: 1075-62-3) belongs to pyridine derivatives. Pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJ·mol−1 in pyridine vs. 150 kJ·mol−1 in benzene). Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Formula: C7H9N3O
