The synthesis of an original electrophilic difluoromethylating reagent was successfully achieved upon a straightforward protocol (3 steps). Like a Swiss army knife, this bench-stable reagent allowed the functionalization of various classes of compounds under mild and transition metal-free conditions. Hence, an efficient and operationally simple tool for the construction of C(sp2)-, C(sp3)- and S-CF2SO2Ph
通过简单的方案(3 个步骤)成功合成了原始亲电子二氟甲基化试剂。就像瑞士军刀一样,这种稳定的试剂可以在温和且不含过渡金属的条件下对各类化合物进行官能化。因此,提供了用于构建C(sp 2 )-、C(sp 3 )-和S -CF 2 SO 2 Ph键的有效且操作简单的工具,扩展了含PhSO 2 CF 2分子的化学空间。生物活性分子的后期功能化以及利多卡因的PhSO 2 CF 2 - 和HCF 2 -类似物的合成也已成功实现。
