Ir-catalyzed Asymmetric Hydrogenation of α-Imino Esters with Chiral Ferrocenylphosphine-Phosphoramidite Ligands

An Ir-catalyzed asymmetric hydrogenation of α-imino esters with unsymmetrical hybrid chiral ferrocenylphosphine-phosphoramidite ligands for the synthesis of optically active α-aryl glycines has been described. The result indicated that the presence of the iodo-substitutent at the 3/3’-position of the binaphthyl unit of ligand could significantly improve the catalytic performance. This method features high asymmetric induction and reasonable functional group tolerance, thus providing a concise and efficient approach toward chiral α-aryl glycine derivatives with up to 96% ee.

Chiral phosphine-phosphoramidite ligands for highly efficient Ir-catalyzed asymmetric hydrogenation of sterically hindered N-arylimines

A mild and general iridium-catalyzed, highly enantioselective hydrogenation of sterically hindered N-arylimines with a new H8-BINOL-derived phosphine-phosphoramidite ligand has been developed. The present catalytic system features high turnover numbers (up to 100000) and good to perfect enantioselectivities (up to 99% ee) for the hydrogenation of a variety of sterically hindered N-arylimines.
