Synthesis of 7-aryl-1,8-naphthyridines via addition of aryl boronic acids to 1,8-naphthyridine N-oxides

Synthesis of 1,8-Naphthyridines by the Ionic Liquid-Catalyzed Friedlander Reaction and Application in Corrosion Inhibition

“…Thus, a convenient, rapid, environmentally friendly, and high-yielding synthetic method was designed using ionic liquids (ILs) as reaction media as well as promoters to synthesize 1,8naphthyridine without any added catalyst or solution because ILs have interesting properties such as a wide liquidus range, 23 good solubility of solutes, 24 low saturated vapor pressure, 25 and excellent catalytic activity and recyclability. 26 1,8-naphthyridyl complexes with unique structures have been extensively applied in pharmaceuticals, 27,28 molecular recognition, 29 fluorescence sensors, 30,31 as well as in the fields of organic chemistry. 32 However, as far as we know, there are almost no reports about their use as a corrosion inhibitor.…”
