PURPOSE: Provided are a chiral salen derivative bonded to a polymer and a chiral salen-metal complex produced from the chiral salen derivative polymer, wherein the chiral salen-metal complex is used as a chiral catalyst in an asymmetric epoxidation of olefin. CONSTITUTION: The chiral salen derivative is represented by the formula 1 and the chiral salen-metal complex is represented by the formula 5, wherein m is 0 or 1, n is an integer of 0-24, Y is O, NH, or C(O)NH, p is a polymer insoluble in water and organic solvents, H(1) and H(2) are trans each other, M is a transition metal ion selected from the group consisting of Cr, Mn, V, Fe, Mo, W, Ru, Co, Ti, and Os, and A is an anion selected from the group consisting of Cl-, CH3COO-, PF6-, and SbF6-.
