The synthesis of diverse substituted indole structures on solid supports is described. The immobilization of nitrobenzoic acid onto Merrifield resin and the subsequent treatment with alkenyl Grignard reagents delivered indole carboxylates bound to solid supports. In contrast to results in the liquid phase, ortho,ortho-unsubstituted nitroarenes also delivered indole moieties in good yields. Subsequent
描述了在固体支持物上合成多种取代的吲哚结构。将硝基苯甲酸固定在 Merrifield 树脂上并随后用链烯基格氏试剂处理将吲哚羧酸盐结合到固体载体上。与液相中的结果相反,邻位、邻位未取代的硝基芳烃也以良好的产率递送吲哚部分。随后的钯催化反应(Suzuki、Heck、Sonogashira、Stille)在裂解后通过四个步骤以中等至良好的产率传递所需的分子。介绍了范围和限制。
