Free amino group-directed C(sp3)–H functionalization of aliphatic amines is a fundamental challenge in synthetic organic chemistry. Also, the NH2-directed C(sp3)–H functionalization of α-amino acids and their derivatives remains barely explored. With palladium as the catalyst and Ag2O as the additive, we developed the first NH2-directed γ-C(sp3)–Harylation of α-amino esters with diaryliodonium triflates
