An efficient metal-free organocatalytic activation of hydrogen peroxide (H2O2) towards thioethers leading to the corresponding sulfoxides in high yields at room temperature within hours was promoted by the hexameric capsule formed by
Biotransformation of organic sulfides. Part 12. Conversion of heterocyclic sulfides to chiral sulfoxides by Helminthosporium sp. NRRL 4671 and Mortierella isabellina ATCC 42613

The Sharpless reagent for asymmetric epoxidation was modified by addition of 1 mol equiv of H2O to give a new homogenous reagent (Ti(O-i-Pr)4/diethyl tartrate/H2O/t-BuOOH = 1:2:1:1).This reagent cleanly oxidizes prochiral functionalized sulfides into optically active sulfoxides.The observed ee mainly ranged between 75 and 90percent for alkyl aryl sulfoxides and 50-71percent for dialkyl sulfoxides.A strong temperature dependence on ee was also observed in the asymmetric oxidation of methyl p-tolyl sulfoxide.
