在此,我们报道了第一个可见光光氧化还原催化芳基环氧化物与 CO 的羧化反应来合成羟基酸衍生物。在温和条件下以中等到高产率获得多种有价值的β-、γ-、δ-、ε-羟基酸衍生物。该方案显示出值得注意的官能团相容性,在无过渡金属条件下具有高化学和区域选择性,并使用廉价的有机染料作为光敏剂。机理研究表明,苄基碳负离子是作为顺序单电子转移(SSET)过程的中间产物而产生的。

Novel copper-catalyzedaerobic synthesis of aryl nitriles and aldehydes from epoxides via C-C single bond cleavage has been discovered. This reaction provides a practical method toward the synthesis of aryl nitriles and aldehydes, which are versatile intermediates and building blocks in organic synthesis.
