, p. 5063 - 5068 (2019)
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.
