Abstract
MCM-41 anchored 1,4-bis(9-O-quininyl)phthalazine (MCM-(QN)2PHAL)-OsO4, 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, K3Fe(CN)6 or molecular oxygen as cooxidants.
