Asymmetric oxidation of sulfide to sulfoxides on Ti-containing mesoporous silica catalysts with hydrogen peroxide in the presence of optically active tartaric acid
On Ti-containing MCM-41 prepared by a template ion-exchange method, sulfide could be asymmetrically oxidized to sulfoxides in the presence of optically active tartaric acid (54% yield and 30% ee). The oxidation was composed of the asymmetric induction to sulfoxides and the subsequent kinetic resolution of sulfoxides.
