formation. Herein, we report a biomimetic approach that converts phenolic CH bonds into CO, CN, and CS bonds at the sole expense of reducing dioxygen (O2) to water (H2O). Our method hinges on a regio‐ and chemoselective copper‐catalyzed aerobic oxygenation to provide ortho‐quinones. ortho‐Quinones are versatile intermediates, whose direct catalytic aerobic synthesis from phenols enables a mild and efficient
芳香族CO,CN和CS键的重要性使形成它们的策略日益有效。本文中,我们报道了一种仿生方法,该方法可将酚的CH键转换为CO,CN和CS键,而唯一的代价就是将双氧(O 2)还原为水(H 2 O)。我们的方法取决于区域和化学选择性铜催化的需氧氧化,以提供邻醌。邻位喹诺酮是通用的中间体,其从苯酚的直接催化有氧合成可提供温和而有效的合成多官能芳环的方法。
