The asymmetrictransferhydrogenation of imines was performed with the use of a polymer-immobilized chiral catalyst. The chiral catalyst, prepared from crosslinked polystyrene-immobilized chiral 1,2-diamine monosulfonamide, was effective in the asymmetrictransferhydrogenation of N-benzyl imines in CH2Cl2 to give a chiral amine in high yield and good enantioselectivity. Furthermore, an amphiphilic
