Abstract:

Catalytic asymmetric epoxidation of alkenes is a powerful method for the synthesis of chiral organic compounds. A recyclable chiral Jacobsen's catalyst immobilized on ZnPS-PVPA on diamines gave high catalytic activity(conversion > 99%, ee > 99%) in the asymmetric epoxidations of unfunctionalized olefins. The synergistic effect of the support ZnPS-PVPA and the linkage as well as chiral salen Mn center contributed to the chirality of the product. The stability(recycled nine times) and the ease of use in large scale reactions(200 times scale) indicated a catalyst useful for industrial use.
