Herein, we report a method that combines hydrogen atom transfer and photoredox catalysis to achieve the dehydrogenative difluoroallylation of amides, ethers, and alkyl aldehydes. This operationally convenient method transforms a broad scope of substrates into the corresponding gem-difluoroalkenes via the construction of C(sp3)–C(sp3) or C(sp3)–C(sp2) bonds. Excellent functional group compatibility
本文中,我们报告了一种结合氢原子转移和光氧化还原催化以实现酰胺,醚和烷基醛脱氢二氟烯化的方法。通过C(sp 3)–C(sp 3)或C(sp 3)–C(sp 2)键的构建,这种操作方便的方法可将多种底物转化为相应的宝石-二氟烯烃。出色的官能团相容性和高选择性使该方法具有广泛的底物类型,使其适用于药物中间体的后期修饰。
