A palladium(II)-catalyzed enantioselective arylation of unbiased secondaryC(sp3)–H bonds was developed. The enantioselectivity was controlled by the combination of a pyridyl or isoquinolinyl directinggroup and an amino acid, N-Boc-2-pentyl proline. A variety of 2-propyl azaaryls and biaryl iodides were employed to provide arylated products in moderate to good yields (up to 82%) with high enantioselectivities
