stable bioisostere of an amino (NH2) group. Therefore, methods that can rapidly convert an NH2 group into a CF2H group would be of great value to medicinal chemistry. We report herein an efficient Cu‐catalyzed approach for the conversion of alkyl pyridinium salts, which can be readily synthesized from the corresponding alkyl amines, to their alkyl difluoromethane analogues. This method tolerates a broad
二氟甲基(CF 2 H)被认为是氨基(NH 2)基团的亲脂性和代谢稳定的生物等排体。因此,能够将NH 2基快速转化为CF 2 H基的方法对药物化学具有重要的价值。我们在此报告了一种有效的铜催化方法,用于将烷基吡啶鎓盐(可以轻松地从相应的烷基胺合成)转化为其烷基二氟甲烷类似物。该方法可耐受多种官能团,可用于复杂的含氨基药物的后期修饰。
