We report on a three-component palladium-catalyzed coupling strategy for accessing a wide range of 1,4-diketones, which represent important precursors to heterocycles. Our method relies on a carbonylative Heck reaction employing substituted allylic alcohols, aryl iodides, and carbon monoxide. The reaction conditions are mild and do not require high CO pressure, and a wide functional group tolerance
我们报告了一种三组分钯催化的偶联策略,可用于广泛的1,4-二酮,这些化合物代表杂环的重要前体。我们的方法依赖于采用取代的烯丙醇,芳基碘化物和一氧化碳的羰基Heck反应。反应条件温和并且不需要高的CO压力,并且揭示了宽的官能团耐受性,以中等至良好的产率提供了所需的1,4-二酮。此外,该方法适用于在羰基位置之一或两个位置选择性地安装13 C-碳同位素。
