<jats:title>ABSTRACT</jats:title><jats:p>This article details the enantioselective catalytic performance of crosslinked, polymer immobilized, Ir‐based, chiral complexes for transfer hydrogenation of cyclic imines to chiral amines. Polymerization of the achiral vinyl monomer, divinylbenzene, and a polymerizable chiral 1,2‐diamine monosulfonamide ligand followed by complexation with [IrCl<jats:sub>2</jats:sub>Cp*]<jats:sub>2</jats:sub> affords the crosslinked polymeric chiral complex, which can be successfully applied to asymmetric transfer hydrogenation of cyclic imines. Polymeric catalysts prepared from amphiphilic achiral monomers have high catalytic activity in the reaction and can be used both in organic solvents and water to give chiral cyclic amines with a high level of enantioselectivity (up to 98% ee). The asymmetric reaction allows for reuse of the heterogeneous catalyst without any loss in activity or enantioselectivity over several runs. © 2014 Wiley Periodicals, Inc. J. Polym.
