  Enantioselective Formal Aza-Diels–Alder Reactions of Enones with Cyclic Imines Catalyzed by Primary Aminothioureas

  摘要：

  A highly enantio- and diastereoselective synthesis of indolo- and benzoquinolizidine compounds has been developed through the formal aza-Diels-Alder reaction of enones with cyclic imines. This transformation is catalyzed by a new bifunctional primary aminothiourea that achieves simultaneous activation of both the enone and imine reaction components.

• Intermolecular Regio‐ and Stereoselective Hetero‐[5+2] Cycloaddition of Oxidopyrylium Ylides and Cyclic Imines

  We have developed the first intermolecular hetero‐[5+2] cycloaddition reaction between oxidopyrylium ylides and cyclic imines with excellent control of regio‐ and stereoselectivity. Surprisingly, divergent stereochemistry was observed depending on the substitution pattern of the oxidopyrylium ylide. This new reaction provides quick access to highly substituted nitrogen‐containing seven‐membered rings—azepanes

  我们开发了第一个分子间异[5 + 2]环氧化吡啶鎓和环状亚胺之间的杂分子间[5 + 2]环加成反应，可很好地控制区域选择性和立体选择性。出乎意料的是，根据氧化吡啶鎓叶立德的取代模式观察到不同的立体化学。这种新的反应使人们可以快速进入高度取代的含氮七元环-氮杂环丁烷。值得注意的是，广泛的氧化吡啶鎓基团和环状亚胺参与了这种新型的异[5 + 2]环加成反应，并且环加合物可以轻松转化为生物活性天然产物的核心骨架。DFT计算表明，环加成反应通过逐步途径进行，亚胺氮原子充当亲核试剂以引发环加成反应。
