A new chiral tridentate PNN ligand, indan-f-amphox (a sister ligand of f-amphox), was synthesized and applied in iridium-catalyzed asymmetric hydrogenation of β-aryl β-ketoesters. A wide range of β-aryl β-ketoesters are reduced using an Ir(III)-indan-f-amphox catalyst with excellent enantioselectivities and reactivities (up to 99% ee, TON=10000).

Key words: PNN ligand, asymmetric hydrogenation, β-ketoesters, f-amphox
