The acid‐catalysed thermal rearrangements of a family of N‐aryl 2‐azabicyclo[3.1.0]hexanes is described. These substrates, designed in such a way that the aromatic system is conjugated with an alkene group located at the ortho position relative to the nitrogen atom, have been prepared by using an intramolecular Kulinkovich–de Meijere reaction. The rearrangements can then be conducted either under standard
描述了N-芳基2-氮杂双环[3.1.0]己烷家族的酸催化热重排。这些底物的设计方式是使芳族体系与位于邻位的烯基共轭通过使用分子内Kulinkovich-de Meijere反应制备相对于氮原子的位置。然后可以在标准热条件下或在微波激活下进行重排。根据所施加的条件和取代方式,可以获得二氢喹啉或多环氨基环丁烷衍生物。提供了机械学的讨论,提出了氨基环丙烷部分的初始质子化以生成亚胺基中间体的提议。类似于相关的分子间反应,提出了一系列后续基本步骤中涉及的电环反应。
