efficient intermolecular reaction of gold carbene intermediates, generated via gold-catalyzed alkyne oxidation, with indoles and anilines has been realized in aqueous media. Importantly, it was revealed for the first time that water could dramatically suppress the undesired over-oxidation, providing a general and practical solution to the problem of over-oxidation in gold-catalyzed intermolecular alkyne
在水介质中已经实现了通过金催化的炔烃氧化产生的金卡宾中间体与吲哚和苯胺的有效分子间反应。重要的是,这首次揭示了水可以显着抑制不希望的过氧化,从而为使用外部亲核试剂的金催化的分子间炔烃氧化中的过氧化问题提供了一种通用且实用的解决方案。该策略已成功应用于辉瑞手性内皮素拮抗剂UK-350,926的正式合成。
