3-triazolyl-1,2,4-triazol-3(4H)-ones 8j-v were synthesized by click chemistry as an ultimate tactic where [3 + 2] cycloaddition of azides with terminal alkynes has been evolved. Herein, we are inclined to divulge the implication and prevalence of CuSO4·5H2O and THF/water promoted [3 + 2] cycloaddition reactions. The foremost supremacy of this method are transitory reaction times, facile workup, excellent
Quinolin-3-yl-methyl-1,2,3-triazolyl-1,2,4-triazol-3(4 H )-ones 8j-v 是通过点击化学合成的,作为一种最终的策略,其中 [3 + 2] 环加成具有末端炔烃的叠氮化物已经得到发展。在此,我们倾向于透露 CuSO 4 ·5H 2的含义和流行程度O 和 THF/水促进了 [3 + 2] 环加成反应。这种方法的首要优势是短暂的反应时间、简便的后处理、优异的产率 (88-92%)、超高的纯度和在常规和微波方法下的区域选择性单产物形成。对接研究通过高 C 值说明了与酶 InhA-D148G(PDB ID:4DQU)的强结合相互作用。合成化合物的抗结核和抗真菌筛选显示出有希望的活性。在体外和在计算机芯片上的研究暗示这些三唑所附喹啉可获取理想的结构为先决条件的新的治疗剂的辅助膨胀。
