  结合理论和实验研究揭示了烯酰胺聚合不对称氢化的多种途径

  摘要：

  我们提出了一种由 N,P-铱配合物催化的E / Z烯酰胺混合物的高效收敛不对称氢化，并得到机理研究的支持。发现烯烃异构体（E和Z几何形状）的还原产生具有相同绝对构型的手性酰胺（对映收敛氢化）。这允许以优异的对映选择性（高达 99% ee）。使用氘标记和动力学实验的详细机理研究揭示了观察到的对映收敛的两种不同途径。对于 α-芳基烯酰胺，双键发生快速异构化，整个过程导致两种异构体的动力学拆分。对于 α-烷基烯酰胺，没有检测到双键异构化，竞争实验表明底物螯合是对映收敛立体化学结果的原因。进行 DFT 计算以预测产物的正确绝对构型并加强提出的铱催化异构化途径的机制。
