Herein we report a strategy concerning Rh(III)-catalyzed direct ortho-C–H bond carbonylation to construct benzoxazinones from anilines and their derivatives with high atom economy. Interestingly, the corresponding amides were generated in situ from anilines when excess Ac2O was added and directed the following C–H bond carbonylation to form benzoxazinones. Extensive functional group tolerance can be
在此,我们报道了一种Rh(III)催化的直接邻-C-H键羰基化反应,以
苯胺及其高原子经济性衍
生物构建苯并恶嗪酮的策略。有趣的是,当添加过量的Ac 2 O时,
苯胺原位生成相应的酰胺,并引导随后的C-H键羰基化形成苯并恶嗪酮。当安装烷基酰胺导向基团时,可以实现广泛的官能团耐受性。此外,该方法可以方便地对一些带有芳胺基团的药物进行衍生化,显示出其潜在的应用前景。
