| 英文摘要 | 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 systems when substituted styrenes and substituted 2,2-dimethylchromenes were used as substrates. furthermore, the poly-salen-mn(iii) complexes could be recovered easily and recycled efficiently several times by a simple catalysis/separation method. after five reactions, an 82% ee and 78% yield of epoxide were obtained using 2,2-dimethylchromene as substrate.
