A simple cost-effective and green method was presented for the synthesis of coumarin bis sulfonamides. Seventeen novel coumarin sulfonamides were synthesized in good to high yield and purity in six steps starting from 2-amino thiazole, aniline, and 4-methoxy aniline. All of the reactions have been done under green conditions without using any hazardous solvent. The chemical structures of the products
提出了一种简单、经济、绿色的香豆素双磺胺类化合物合成方法。从 2-氨基噻唑、苯胺和 4-甲氧基苯胺开始,分 6 步合成了 17 种新型香豆素磺胺类药物,收率高,纯度高。所有反应均在绿色条件下完成,不使用任何有害溶剂。产物的化学结构通过IR、1 H NMR和13 C NMR光谱和元素分析阐明。此外,使用两种葡萄球菌(革兰氏阳性)和大肠杆菌(革兰氏阴性)细菌菌株研究了合成磺胺类药物的抗菌特性。
