The Cp*Rh(III)-catalyzed indazolone-directed C−H bond amidation of arenes has been realized by employing sulfonyl azide agents and dioxazolones as nitrogen source. This protocol displays mild conditions, broad substrate scope and high functional group compatibility. What’ more, the late-stage modifications of structure complicated drugs, such as Gemfibrozil, Oxaprozin, Probenecid and Naproxen, has
通过使用磺酰叠氮剂和二恶唑酮作为氮源,已经实现了 Cp*Rh(III) 催化的吲唑酮定向 C-H 键酰胺化芳烃。该协议表现出温和的条件、广泛的底物范围和高官能团兼容性。此外,吉非罗齐、奥沙普秦、丙磺舒、萘普生等结构复杂药物的后期修饰也得到了证实。此外,还提出了初步的机理研究和探索性反应机理。
