molecule synthesis. However, only a limited amount of examples are known for most functional groups. Herein, we describe such an unusual process of oxetanes. In the presence of In(OTf)3 as catalyst, oxetane‐tethered anilines reacted unexpectedly to form 1,2‐dihydroquinolines. This process not only provides expedient access to dihydroquinolines, but also represents a new reaction of oxetane. Mechanistically
骨骼重组由于其有趣的机制和在复杂分子合成中的实用性而成为一种引人入胜的转化。然而,对于大多数官能团而言,仅有限数量的实例是已知的。在此,我们描述了氧杂环丁烷的这种异常过程。在In(OTf)3作为催化剂的存在下,氧杂环丁烷系苯胺意外反应形成1,2-二氢喹啉。该方法不仅提供了方便的二氢喹啉的途径,而且代表了氧杂环丁烷的新反应。从机理上讲,据信反应是通过最初的氮攻击而不是芳烃攻击进行的,随后是一系列的键断裂和形成事件。对照实验提供了对该机理的重要见解。
