Highly diastereoselective and enantioselective desymmetrization of α-substituted cyclohexadienones via NHC-catalyzed intramolecular Stetter reaction was realized. Amino-indanol derived triazolium salt bearing a C(6)F(5) group was found to be the optimal catalyst precursor in the intramolecular Stetter reaction furnishing tricyclic products bearing multi-stereocenters in up to 96% yield and >99% ee.
通过 NHC 催化的分子内环 Stetter 反应，实现了 α-取代环己二烯酮的高非对映选择性和对映选择性去对称化。研究发现，带有 C(6)F(5)基团的氨基茚醇衍生的三唑翁盐是分子内环 Stetter 反应的最佳催化剂前体，可提供高达 96%收率和>99%ee 的多立体中心的三环产物。
