  使用 CuH 催化高对映选择性合成具有 C3-四元手性中心的吲唑

  摘要：

  C3 取代的 1H-吲唑是许多药物中有用且重要的子结构。与为更亲核的 N1 和 N2 位置开发的反应相比，吲唑直接 C3 官能化的方法相对较少。在此，我们报告了使用 CuH 催化的 1H-N-（苯甲酰氧基）吲唑的高度 C3 选择性烯丙基化反应。各种具有四元立体中心的 C3-烯丙基 1H-吲唑被高效地制备，具有高水平的对映选择性。进行密度泛函理论 (DFT) 计算以解释吲唑和吲哚亲电试剂之间的反应性差异，后者用于我们之前报道的方法中。计算表明，吲唑烯丙基化反应通过决定对映选择性的六元 Zimmerman-Traxler 型过渡态进行，而不是我们在吲哚烷基化的情况下提出的氧化加成/还原消除序列。该反应的对映选择性受配体-底物空间相互作用和空间排斥两者的控制，这些相互作用涉及六元烯丙基化过渡态中的假多轴取代基。
