Synthesis of phenazine derivatives from the reaction of 2-naphthols with 1, 2-diamino benzenes in presence of K2S2O8 in AcOH and water, through the intermediate formation of 1, 2-naphthoquinones from self-coupling of 2-naphthol and then followed by condensation of 1, 2-diamino benzenes in one pot. The present reaction was compatible with various substituted 2-naphthols as well as substituted 1, 2-diamino
在K 2 S 2 O 8存在下由2-萘酚与1,2-二氨基苯的反应合成吩嗪衍生物在AcOH和水中,通过从2-萘酚的自偶联中间形成1,2-萘醌,然后在一个锅中缩合1,2-二氨基苯而形成。本反应与各种取代的2-萘酚以及取代的1,2-二氨基苯相容,从而以良好或优异的收率获得了各种取代的吩嗪衍生物。在不对称取代的1,2-二氨基苯的情况下,该反应是高度区域选择性的,以提供单个区域异构的吩嗪化合物。反应条件也温和且不含金属,还使用了绿色溶剂,例如AcOH和水。吩嗪衍生物是一类重要的杂环,同时存在于天然和合成化合物中,这些化合物显示出许多生物活性,并且还存在于许多重要的染料中。与此同时,我们还显示出我们对抗菌,消炎活性和分子对接研究的兴趣。重要的是要注意,吩嗪衍生物表现出出色的抗菌和抗炎活性。 图形摘要
