Novel tricyclic 4‐(trifluoromethyl)‐[1,2,3]triazolo[1,5‐a]quinoxalines were readily prepared from N‐(o‐haloaryl)alkynylimines and sodium azide via copper(I)‐catalyzedtandem reactions. This synthetic strategy provides an efficient way to access a library of novel heterocyclic compounds that are of interest in drug discovery.
新型三环4-(三氟甲基)-[1,2,3]三唑并[1,5- a ]喹喔啉可通过铜(I)催化的串联反应由N-(邻-卤代芳基)炔基亚胺和叠氮化钠制得。这种合成策略提供了一种有效的方法来访问在药物开发中感兴趣的新型杂环化合物的库。
