therefore, various synthetic methods for indole functionalizations have arisen in recent years. Herein, we report a Pd-catalyzed deoxygenative coupling for the N-vinylation of indoles by employing vinyl ethers. The vinylated indoles could be readily prepared in good to excellent yields with N1-regioselectivity regardless of the electronic characteristics and substitution patterns of indole substrates
吲哚是一种在许多天然产物和药物中很有前途的杂芳烃;因此,近年来出现了各种吲哚官能化的合成方法。在此,我们报道了使用乙烯基醚进行吲哚N-乙烯基化的 Pd 催化脱氧偶联。无论吲哚底物的电子特性和取代模式如何,乙烯基化吲哚都可以很容易地以良好到优异的产率制备,并具有 N1 区域选择性。一些基于吲哚的药物分子,如禾本科胺、吴茱萸碱、吴茱萸碱和褪黑激素也成功地乙烯基化。此外,咔唑和吲唑也被证明参与其中。此外,乙烯基化吲哚可以很容易地转化为结构有趣的吲哚衍生物。
