acceleration effect of spiro bis(isoxazoline) ligand (SPRIX) on the Pd(II)-catalyzed intramolecular aminocarbonylation of alkenyl amine derivatives was realized. Furthermore, the chiral Pd(II)–SPRIX catalyst accomplished the first enantioselective intramolecular aminocarbonylation. The reaction of N-(2,2-dimethyl-pent-4-enyl)-p-toluenesulfonamide in the presence of Pd(II)–SPRIX catalyst and p-benzoquinone in
