  环氧-开放醚环化成不同大小的环的主要阴离子-π催化：获得新的反应性。

  摘要：

  阴离子-π催化的概念集中在芳族π表面上阴离子过渡态的稳定化。最近，我们证明了在芳香族π表面上环氧化物开放醚环化的发生。尽管反应是通过非常规机制进行的，但所得产物与常规布朗斯台德酸催化的产物相同，并且符合鲍德温选择性规则。然而，不同的机制最终应该导致新产品的出现，阴离子-π催化一直不愿实现。在本文中，我们报告了在可比条件下适用于阴离子-π催化而不适用于布朗斯台德酸的非平凡反应。即，我们证明了阴离子-π模板化的自催化和具有醇盐-π相互作用的环氧化物开环可以提供非常规环化学的途径。对于较小的环，阴离子-π催化作用可提供抗鲍德温氧杂环戊烷，2-氧杂双环[3.3.0]辛烷，以及通过甲基迁移使鲍德温氧杂环丁烷膨胀。对于较大的环，阴离子-π模板自催化被认为减轻了折叠的熵损失，从而使不利的反鲍德温环化成为氧杂环丁烷和氧杂环丁烷。
