Herein we report acid‐directed β‐C(sp3)‐Harylation of α‐amino acids enabled by pyridine‐type ligands. This reaction does not require the installation of an exogenous directinggroup, is scalable, and enables the preparation of Fmoc‐protected unnatural amino acids in three steps. The pyridine‐type ligands are crucial for the development of this new C(sp3)‐Harylation.
