despite the recent advances in the fields of both C–H and C–C bond activation. Herein, we report a palladium-catalyzed migrative carbofluorination of saturated amides enabled by the activation of both the C(sp3)–H and the Cquaternary–Cσ bonds. In this transformation, the α-quaternary carbon of Weinreb amides is converted to α-tertiary fluoride with concurrent migration of an aryl or an amido group from
尽管最近在 C-H 和 C-C 键活化领域取得了进展,但直接编辑非应变无环分子的全碳季碳本身仍未得到充分利用。在此,我们报告了通过激活 C(sp 3 )-H 和 C季-Cσ 键实现的钯催化的饱和酰胺的迁移碳氟化反应。在这种转变中,Weinreb 酰胺的 α-季碳转化为 α-叔氟化物,同时芳基或酰胺基从 α-碳迁移到 β-碳。DFT 计算表明,电致重排通过一个不寻常的反-选择性[2.1.0]双环过渡态。该反应与多种官能团相容,具有立体专一性,适用于对映体富集产物的合成。
