photoredox/nickel dual catalysis to access chiral products with good yield and enantioselectivity. The operationally simple reaction was carried out under mild conditions with good functional group tolerance. Due to the use of a stoichiometric equivalent of aryl/alkenyl halides as coupling partners, the sequential and iterative synthesis could be achieved smoothly in one pot for the synthesis of position
在此,我们报道了通过光氧化还原/镍双重催化与1,4-二氢吡啶(DHP)衍生物进行对映会聚的Csp 3 -Csp 2交叉偶联反应,以良好的收率和对映选择性获得手性产物。该反应操作简单,条件温和,官能团耐受性良好。由于使用化学计量当量的芳基/烯基卤化物作为偶联伙伴,可以一锅顺利地实现顺序和迭代合成,以合成位置异构体和立体异构体。在所提出的机制中,动力学实验和机理研究表明,自由基的产生取决于激发的光催化剂和 DHP,是速率决定步骤。
