被撤回的出版物: Olefin epoxidation with chiral salen Mn(III) immobilized on ZnPS-PVPA upon alkyldiamine (Retracted article. See vol. 10, pg. 43010, 2020)

The asymmetric epoxidation of unfunctionalized olefins using Jacobsen's catalyst is an effective strategy to achieve chiral epoxides. We report Jacobsen's catalysts anchored onto ZnPS-PVPA upon alkyldiamines as active heterogeneous catalysts for the epoxidation of unfunctionalized olefins (conv%, up to >99; ee%, up to >99). These new heterogenized catalysts not only could be reused nine times with no variation in performance but also display high performance in large-scale reactions, which presents practical applications in high-throughput organic chemistry.
