Herein, we demonstrate the first nickel-catalyzed double dehydrogenative condensation of secondary alcohols and β-amino alcohols in one pot to the pyrrole derivatives. A series of 2,5- and 2,3,5-substituted pyrroles were obtained in ≤83% yield, releasing water and hydrogen gas as byproducts. Initial mechanistic studies, including defined Ni catalyst, deuterium labeling experiments, quantitative determination
在本文中,我们证明了在一个罐中仲醇和β-氨基醇第一次与镍催化的双脱氢缩合成吡咯衍生物。获得了一系列2,5和2,3,5-取代的吡咯,产率≤83%,释放出水和氢气作为副产物。进行了初步的机理研究,包括确定的Ni催化剂,氘标记实验,氢气定量评估以及反应混合物中水的生成的检测。
