Herein we report a nickel-catalyzed aryl addition/intramolecular esterification in a cascade fashion. Under the combination of commercially available nickel precursor and tridentate ligand, the one pot protocol offers a direct, simple and regioselective approach to access 3-aryl phthalide derivatives from two readily available substrates with good efficiency, broad scope as well as satisfactory functional
在此,我们以级联方式报告了镍催化的芳基加成/分子内酯化。在市售镍前体和三齿配体的组合下,一锅方案提供了一种直接、简单和区域选择性的方法,可以从两种现成的基质中获得 3-芳基苯酞衍生物,具有良好的效率、广泛的范围以及令人满意的官能团兼容性。
