developed a highly efficient catalytic enantioselective fluorination of oxindole derivatives. In the presence of a catalytic amount of chiral Pd complex 2 (2.5 mol %), various substrates, including aryl- and alkyl-substituted oxindoles, were fluorinated in a highly enantioselective manner (up to 96% ee). In addition, when R was a hydrogen atom, enantioselective fluorination followed by solvolysis gave
我们开发了一种高效催化对映选择性氟化的羟吲哚衍生物。在催化量的手性 Pd 配合物 2 (2.5 mol%) 存在下,各种底物,包括芳基和烷基取代的羟吲哚,以高度对映选择性的方式(高达 96% ee)氟化。此外,当 R 是氢原子时,对映选择性氟化然后溶剂分解得到单氟化酯,ee 高达 93%。据我们所知,这是羟吲哚催化对映选择性氟化的第一个例子。
