Ir-catalyzed Asymmetric Hydrogenation of alpha-Imino Esters with Chiral Ferrocenylphosphine-Phosphoramidite Ligands
An Ir-catalyzed asymmetric hydrogenation of alpha -imino esters with unsymmetrical hybrid chiral ferrocenylphosphine-phosphoramidite ligands for the synthesis of optically active alpha -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 alpha -aryl glycine derivatives with up to 96% ee
