Herein we describe a method for combining supramolecular catalysis with imininum-based organocatalysis in the Diels–Alder cycloaddition reaction. Both supramolecular host and L-proline are required for the reaction to occur, implying that encapsulation of the substrates and co-catalyst are necessary for the reaction to occur. We explore the substrate scope for a variety of E-cinnamaldehydes and dienes
在此,我们描述了一种在狄尔斯-阿尔德环加成反应中将超分子催化与基于亚胺的有机催化相结合的方法。超分子主体和L-脯氨酸都是反应发生所必需的,这意味着底物和助催化剂的封装对于反应的发生是必要的。我们探索了各种E-肉桂醛和二烯的底物范围。最后,我们使用核磁共振波谱方法探讨了负责观察到的催化作用的超分子组装过程。
