Fully loaded: A coordinating activation strategy has been developed to furnish α‐quaternary α‐amino acids through the iron(III)‐catalyzed oxidative functionalization of α‐C(sp3)H bonds of α‐tertiary α‐amino acid esters. The reaction exhibits a broad substrate scope for both α‐amino acids and nucleophiles (Nu) as well as good functional‐group tolerance (see scheme, DTBP=di‐tert‐butyl peroxide, DCE=1
