MCM-41 Anchored Cinchona Alkaloid for Catalytic Asymmetric Dihydroxylation of Olefins: A Clean Protocol for Chiral Diols Using Molecular Oxygen
摘要：
MCM-41 anchored 1,4-bis(9- O -quininyl)phthalazine (MCM-(QN) 2 PHAL)-OsO 4 , is prepared for the first time and used in the heterogeneous asymmetric dihydroxylation of olefins to afford diols with good to excellent enantiomeric excesses in the presence of N -methylmorpholine N -oxide, K 3 Fe(CN) 6 or molecular oxygen as cooxidants.
