Two novel chiral poly-salen-Mn(III) complexes 1 and 2, derived from (R,R)-1,2-diaminocyclohexane and the disalicylaldehydes 5 and 6 were synthesized and employed in the enantioselective epoxidation of olefins. A range of 30-92% ee and 75-97% yield was achieved in NaClO/4-PPNO and m-CPBA/NMO oxidant
