    草酸环戊烷缩醛的非对映选择性亲核取代反应:“内部攻击”模型在五元环氧碳鎓离子反应中的应用。
    摘要:
    在大多数情况下,将亲核试剂添加到由氧杂硅环戊烷乙酸酯衍生的氧碳鎓离子上时,非对映选择性很高。立体要求高的亲核试剂,例如二乙基酮的甲硅烷基烯醇醚,与C-2取代基相对。这些反应建立了关于新形成的碳-碳键的顺式立体化学。小亲核试剂(例如烯丙基三甲基硅烷)没有显示出相同的立体化学偏好:它们从与C-2-取代的氧碳鎓离子中的取代基相同的面添加。小和大亲核试剂都表现出的立体选择性可以通过应用“内部攻击”模型(先前开发用于四氢呋喃衍生的阳离子的五元环氧碳鎓离子)来理解。这种立体电子模型需要从阳离子表面进攻亲核试剂,从而以较低的能量交错构象提供产物。小型亲核试剂增加了氧碳鎓离子的低能基态构象异构体的“内部”。相反,空间要求高的亲核试剂会添加到包膜构象异构体的内部,而无论基态构象异构体的数量如何,该方法都与氧碳鎓离子的C-2取代基相反。
