The intramolecular Rauhut−Currier reaction creates a carbon−carbon bond between two tethered Michael acceptors. Previous asymmetric versions have relied on 1,4-additions of chiral nucleophilic catalysts. Herein, we investigate a novel strategy that involves the formation of electron rich dienamines as key intermediates. Our methodology provides an efficient entry to the iridoid framework.
分子内的Rauhut-Currier反应在两个拴在一起的Michael受体之间建立了碳-碳键。先前的不对称形式依赖于手性亲核催化剂的1,4-加成。在本文中,我们研究了一种新型策略,其中涉及形成富电子的二烯胺作为关键中间体。我们的方法提供了有效的进入虹彩框架的入口。
