在过去的几年中,通过芳基卤化物或三氟甲磺酸酯和胺的交叉偶联使用钯催化的芳香碳氮键形成反应已成为一种有用的合成工具。在这里,我们描述了一种铜(I)催化剂体系,该体系可以有效合成官能化的吲哚和吡咯并[2,3- c ]吡啶。该方法利用氨基酸促进的胺与芳基卤化物的铜偶联,特别是使用CuI-1-脯氨酸催化剂体系。

Silylative dearomatizations of indole-2-carboxylates were accomplished using a copper(I) catalyst and silylboronates. This reaction presumably proceeds through regioselective addition of silylcoppe...

Nitrogen substituted indole-2-carboxylates can be prepared via an intramolecular palladium-catalysed amination reaction of didehydrophenylalanine derivatives using PdCl2(dppf) and KOAc in DMF at 90 degrees C to form the indole nucleus. The specific formation of (Z)-isomers from Horner-Wadsworth-Emmons reaction of phosphonylglycinates and 2-iodobenzaldehydes was crucial to the success of the process, The product N-substituted indole-2-carboxylates were isolated in high yield.
