我们报道了一种高效和可持续的铜(i)乙炔的电化学合成使用同时铜氧化和霍夫曼消除季铵盐。电化学产生的碱也被电化学再生,使其具有催化作用。进行“点击测试”(CuAAC反应)以评估产物纯度,并进行电化学促进的一锅法CuAAC反应,其作为该方法在药学相关反应中的有希望的初步证明。我们报道了一种高效和可持续的铜(i)乙炔的电化学合成使用同时铜氧化和霍夫曼消除季铵盐。
We report an efficient and sustainable electrochemical synthesis of copper(i) acetylides using simultaneous copper oxidation and Hofmann elimination of quaternary ammonium salts. The electrochemically-generated base was also regenerated electrochemically, making it catalytic. A ‘Click test’ (CuAAC reaction) was performed to assess product purity and an electrochemically-promoted, one-pot CuAAC reaction was performed, which serves as a promising initial demonstration of this approach in a pharmaceutically-relevant reaction. We report an efficient and sustainable electrochemical synthesis of copper(i) acetylides using simultaneous copper oxidation and Hofmann elimination of quaternary ammonium salts.
