An efficient, cost effective and green methodology for ipso nitration in the synthesis of the 3-nitro derivative of 3-carboxy 4-quinolones has been developed by the quantitative use of copper acetate and silver nitrate in water. The observed regioselectivity of nitration is explained by the DFT calculations. Three of these compounds with IC50 values (2.9–3.4 μmol) against Brugia malayi thymidylate
通过在水中定量使用乙酸铜和硝酸银,已经开发了一种高效,经济,绿色的ipso硝化方法,用于合成3-羧基4-喹诺酮的3-硝基衍生物。DFT计算解释了观察到的硝化区域选择性。这些化合物中的三种对马来酸胸腺嘧啶激酶的IC 50值为(2.9–3.4μmol),可能是良好的抗丝虫剂,这也通过分子对接研究得到了证明。
