A highly efficient rhodium-catalyzed formal C–H insertion reaction between indoles and 1-diazonaphthoquinones has been established, providing a novel protocol for the atroposelective synthesis of axially chiral C2-arylindoles (up to 99:1 er) under mild reaction conditions. Typically, only 1 mol % of Rh2(S-PTTL)4 is used and the chelation group is not needed for this conversion.

铑催化不对称 C-H 键插入选择性合成轴向手性 C2-芳基吲哚

建立了吲哚和 1-重氮萘醌之间的高效铑催化形式 C-H 插入反应,为在温和反应条件下选择性合成轴向手性 C2-芳基吲哚(高达 99:1 er)提供了新的方案。通常,仅使用 1 mol% 的 Rh 2 ( S -PTTL) 4并且该转化不需要螯合基团。
