A palladium‐catalyzed arylation of unactivated γ‐methylene C(sp3)H and remote δ‐CHbonds by using an oxazoline‐carboxylate directinggroup has been developed. Arylation occurs with a broad substrate scope and high tolerance of functional groups (i.e., halogen, nitro, cyano, ether, trifluoromethyl, amine, and ester). The oxazoline‐type auxiliary can be removed under acidic conditions.
