A greener and more practical strategy for the site-selective C–H arylation of (NH)-indoles via coupling of (hetero)aryl bromides was developed, in which β-cyclodextrin, acting as both a ligand for Na2PdCl4 and a host for indoles, enables the reactions to occur easily in water. The key advantage of this method is the ingenious merging of aqueous homogeneous catalysis and ligand mediation, leading to
开发了一种更环保、更实用的策略,用于通过(杂)芳基溴化物的偶联对 (NH)-吲哚进行位点选择性 C-H 芳基化,其中 β-环糊精作为 Na 2 PdCl 4的配体和吲哚的宿主,使反应在水中容易发生。这种方法的关键优势是水相均相催化和配体介导的巧妙融合,导致具有广泛底物范围和官能团耐受性的 C3-芳基吲哚的高度区域选择性形成。此外,区域选择性可以通过改变碱基的性质而从 C3 位切换到 C2 位,而无需使用 ArI 作为底物。
