  placement of fluorine substituents in the chiral ligand. This approach has led to a new, second-generation family of chiral oxazaborolidinium cationic species which can be used to effect many Diels-Alder reactions in >95% yield and >95% ee using catalyst loadings at the 1-2 mol % level. The easy recovery of the chiral ligand makes the application of these new catalysts especially attractive for large-scale

  手性配体与路易斯酸金属衍生物的配位是对映选择性亲电催化的一种有用策略，通常导致催化活性水平低于原始未络合化合物的催化活性水平。通过进一步将质子或强路易斯酸连接到复合物上进行活化提供了一种克服手性配体失活作用的方法。本文所述的研究表明，通过在手性配体中明智地放置氟取代基，可以进一步提高催化活性。这种方法产生了一个新的第二代手性 oxazaborolidinium 阳离子物种家族，使用 1-2 mol% 水平的催化剂负载量，该物种可用于以 >95% 的产率和 >95% 的 ee 进行许多 Diels-Alder 反应。
