introduction of trifluoromethyl and 1,1-difluoroethyl radicals, generated from their corresponding sulfinate salts, into the C2 position of indole derivatives allows the diastereoselective synthesis of three-dimensional 3,3-spirocyclic indolines over C–H functionalized indoles.
由它们相应的亚磺酸盐生成的三氟甲基和1,1-二氟乙基脱芳香基引入到吲哚衍生物的C2位置,可以在C–H功能化的吲哚上进行非对映选择性的三维3,3-螺环二氢吲哚合成。
