چکیده
A series of tunable axial chiral bisphosphine ligands have been synthesized from (S)-MeO-Biphep. The Ir complex of the MeO-PEG-supported ligand (S)-4k has been successfully applied in asymmetric hydrogenation of quinolines with up to 92% ee. The catalyst system is air-stable and recyclable.

The development of new effective chiral ligands is fundamental to asymmetric hydrogenation. Over recent decades, many excellent bisphosphine ligands have been reported for highly enantioselective hydrogenation reactions. However, the modification of a desired structural motif of most bidentate ligands is impeded by multistep synthesis. Recently, this situation has been partially remedied by the...
