title: Asymmetric oxidation of racemic 2-substituted 1,3-oxathianes.
abstract: Racemic 2-substituted 1,3-oxathianes were oxidized with good to high enantiomer-differentiation by using urea hydrogen peroxide addition compound as oxidant in the presence of a catalytic amount of di-mu-oxo Ti(salen) complex, giving the corresponding sulfoxides diastereoselectively.
