A palladium‐catalyzed arylation of unactivated γ‐methylene C(sp³)H and remote δ‐CH bonds by using an oxazoline‐carboxylate directing group 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.

钯催化未活化的γ-亚甲基C（sp3）的芳基化作用？H和δ-C ？含恶唑啉-羧酸盐助剂的H键

未活化的γ的钯-催化的芳基化-亚甲基C（SP ³） H和远程δ-C  H键通过使用恶唑啉甲酸甲酯定向基团已被开发。在广泛的底物范围和对官能团（即卤素，硝基，氰基，醚，三氟甲基，胺和酯）的高耐受性下发生丙烯酸化。可以在酸性条件下除去恶唑啉型助剂。
