chemistry. Herein an efficient metal-free rearrangement reaction has been developed for the construction of ortho-sulfonamide phenols via HFIP-prompted intramolecular sulfonamide group 1,3-migration. This protocol features mild reaction conditions, broad functional group compatibility and good regioselectivity. Combined experimental mechanistic study and detailed DFT calculations clarified the crucial
邻磺酰胺
酚代表了药物和合成
化学中一类有吸引力的结构基序。本文开发了一种有效的无
金属重排反应,用于通过 HFIP 促进的分子内磺酰胺基团 1,3-迁移构建邻磺酰胺
酚。该方案具有反应条件温和、官能团兼容性广、区域选择性好等特点。结合实验机理研究和详细的 DFT 计算,阐明了 HFIP 分子在促进该反应中的关键作用,并且推导出了独特的氢键网络来解释观察到的反应性。
