Herein, we describe B(C6F5)3/CPA-catalyzed enantioselective aza-Diels–Alder reaction of 3,3-difluoro-2-Aryl-3H-indoles with unactivated dienes to access chiral 10,10-difluoro-tetrahydropyrido[1,2-a]indoles in good yields with good to excellent ee. The resulting cycloadducts containing an CF2 unit could be further transformed into other important building blocks.
在此,我们描述了 B(C 6 F 5 ) 3/ CPA 催化的 3,3-二氟-2-芳基-3 H-吲哚与未活化的二烯的对映选择性氮杂-狄尔斯-阿尔德反应,得到手性 10,10-二氟-四氢吡啶并[1,2- a ]吲哚的产率良好,ee 良好至优异。所得的含有CF 2单元的环加合物可以进一步转化为其他重要的结构单元。
