Rh(II)-catalyzed highly selective N2-arylation of benzotriazole, indazole, and 1,2,3 triazole is developed using diazonaphthoquinone. The developed protocol is extended with a wide scope. In addition, late-stage arylation of these scaffolds tethered with bioactive molecules is explored. Control experiments and DFT calculations reveal that the reaction proceeds presumably via nucleophilic addition of the N2 (of
使用重氮萘醌开发了一种高效的 Rh( II ) 催化的苯并三唑、吲唑和 1,2,3 三唑的高选择性N 2 -芳基化反应。所开发的协议得到了广泛的扩展。此外,还探索了这些与生物活性分子相连的支架的后期芳基化。对照实验和DFT计算表明,该反应可能是通过N 2 (1 H互变异构体)中心与醌型卡宾的亲核加成进行的,然后进行1,5-H转变。
