Asymmetric Baeyer–Villiger oxidation with Co(Salen) and H2O2 in water: striking supramolecular micelles effect on catalysis

A micellar environment enables catalytic, diastereoselective and enantioselective Baeyer–Villiger oxidation of cyclobutanones (ee up to 90%) with H2O2 as oxidant using Co(Salen) catalyst 1, while the same catalytic system is inactive in organic solvents.
