A green and highly efficient synthetic method for the synthesis of quinazoline‐2,4‐diones with hydrogen peroxide as the terminal oxidant has been developed. The reaction features the mild reaction conditions, broad substrate scope, metal‐free catalysts, and sole byproduct water. A plausible mechanism for this process was proposed. Moreover, an antibacterial activity study was performed to evaluate
开发了一种绿色高效的合成方法,以过氧化氢为末端氧化剂合成喹唑啉-2,4-二酮。该反应具有温和的反应条件,广泛的底物范围,无金属催化剂和唯一的副产物水。为此过程提出了一个合理的机制。此外,还进行了一项抗菌活性研究,以使用肉汤微稀释法评估对两种革兰氏阴性细菌菌株(大肠杆菌和肺炎克雷伯菌)和两种革兰氏阳性细菌菌株(表皮葡萄球菌和金黄色葡萄球菌)的抗菌活性。
