Abstract
On Ti-containing MCM-41 prepared by a template ion-exchange method, sulfide could be asymmetrically oxidized to sulfoxides in the presence of opticall y active tartaric acid (54% yield and 30% ee). The oxidation was composed o f the asymmetric induction to sulfoxides and the subsequent kinetic resolut ion of sulfoxides.
