New bidentate auxiliaries derived from the isoxazole-3-carboxamide and oxazole-4-carboxamide moieties were used for Pd-catalyzedC(sp3)–H bond activation. The results show that, when placed on a primary amine compound, 5-methylisoxazole-3-carboxamide (MICA) directsPd-catalyzed activation of inert γ-C(sp3)–H bonds for C–C bond formation. Selective and efficient arylation and alkylation of several α-aminobutanoic
