✦ Synopsis

Asymmetric Oxidation of Dithioacetals and Dithioketals Catalyzed by a Chiral Vanadium Complex.

-The asymmetric oxidation of dithioacetals [cf. (I), (III)] and dithioketals [cf. (V)] using 30% aqueous H 2 O 2 in the presence of VO(acac) 2 and a chiral ligand derived from amino alcohol and salicylaldehyde provides the corresponding monosulfoxides with enantioselectivities of up to 85% e.e. -(BOLM, CARSTEN; BIENEWALD,
