The general synthesis of fully substituted N2-aryl-1,2,3-triazoles is hitherto challenging compared with that of the N1-aryl counterparts. Herein, we describe a Cu-catalyzed annulation reaction of azirines and aryldiazonium salts. This regiospecific method allows access to a broad spectrum of tri-carbo N2-aryl-1,2,3-triazoles substituted with diverse aryl and alkyl moieties. Its utility is highlighted
迄今为止,与N 1-芳基对应物相比,完全取代的N 2-芳基-1,2,3-三唑的一般合成具有挑战性。在本文中,我们描述了铜催化的叠氮化物和芳基重氮盐的环化反应。该区域特异性方法允许获得广泛的被各种芳基和烷基部分取代的三碳N 2-芳基-1,2,3-三唑的光谱。几种适用于药物发现的三唑前体的合成,以及带有三唑部分的新型手性联萘配体,突出了其实用性。
