An efficient regioselective copper-catalyzed strategy for the synthesis of 1,2,3-triazoles from N-tosylhydrazones and azides has been reported. This transformation opened a new route to synthesize 1,2,3-triazoles which is a common structural motif in natural products and pharmaceuticals. The reactions were smoothly under the optimized conditions and provided the desired product in good yields.
已经报道了从N-甲苯磺酰hydr和叠氮化物合成1,2,3-三唑的有效的区域选择性铜催化策略。这一转变开辟了一条合成1,2,3-三唑的新途径,这是天然产物和药物中常见的结构基序。在优化的条件下,反应平稳进行,并以良好的收率提供了所需的产物。
