This paper presents reactions in which the putative cationic intermediate in the Morin rearrangement is trapped by aromatic carbon nucleophiles (indoles and furans). For example, reaction of sulfoxide 27 with trifluoroacetic acid in chloroform provides, among other products, indole 29 and indoline 30. The indoline was shown to be in equilibrium with the nine-membered ring bridged indole 31. Other examples
本文介绍了其中Morin重排中假定的阳离子中间体被芳族碳亲核试剂(吲哚和呋喃)捕获的反应。例如,亚砜27与三氟乙酸在氯仿中的反应可提供吲哚29和二氢吲哚30等。该二氢吲哚显示与九元环桥吲哚31处于平衡状态。莫林重排捕获反应的其他示例介绍了这些转换,并提出了进行这些转换的机制。
