摘要

A process for preparing an optically active cyclic sulfoxide, by reacting a cyclic thioether with cumene hydroperoxide or isopropylcumyl hydroperoxide in the presence of alcohol, water or a mixture of water and alcohol and in the presence of a complex of an optically active tartaric acid diester and a titanium (IV) alkoxide in an inert solvent.
