Abstract
AbstractHerein we reported an efficient photoredox‐catalyzed reaction for site‐selective C(sp3)−H functionalization of carboxamides with silyl enol ethers as radical acceptors. The reaction proceeded through amidyl radical‐directed 1,5‐hydrogen atom transfer (1,5‐HAT) and C(sp3)−C(sp3) bond formation via radical addition of silyl enol ethers. The process features mild conditions and high functional‐group tolerance, allowing the preparation of a series of carboxamides with pendant carbonyl moieties.
