  摘要：

  对 MeOH 诱导的糖醛环氧化物动力学环氧化物开环螺环化的机理研究揭示了简单溶剂在该反应的氢键催化中具有显着的特定作用，以立体选择性地形成螺缩酮产物，并在异头碳上发生构型反转。一系列电子调谐的 C1-芳基乙二醇环氧化物用于研究该反应的机理，该反应基于不同的反应速率和 S(N)2 与 S(N)1 反应歧管的固有偏好。对这些底物的反应动力学的 Hammett 分析与 S(N)2 或 S(N)2 样机制一致（对于这些底物的相应 S(N)1 反应，ρ = -1.3 vs ρ = -5.1）。值得注意的是，螺环化反应二级依赖于甲醇，二级甲醇催化需要糖环氧。然而，丙酮助溶剂是反应的一级抑制剂。提出了与实验数据一致的过渡态，其中一当量的 MeOH 通过氢键激活环氧化物亲电试剂，而第二当量的 MeOH 螯合侧链亲核试剂和糖环氧。一个自相矛盾的先前观察结果，即降低 MeOH 浓度导致竞争性分子间甲基糖苷形成增加，通过发现该副反应仅一级依赖于
