Angew Chem Int Ed Engl 2017; 56:1506-1509.

Abstract
Herein we report acid-directed β-C(sp3 )-H arylation of α-amino acids enabled by pyridine-type ligands. This reaction does not require the installation of an exogenous directing group, 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 )-H arylation.
