Optically active sulfoximines are a promising substance in medicinal chemistry. However, a methodology for preparing chiral sulfoximines in a stereoselective manner has been underdeveloped. Here, we report an asymmetric synthesis of chiral sulfoximines having an aryl group by the newly developed sulfur-selective arylation of easily accessible chiral sulfinamides. The utility of the present method is demonstrated by the asymmetric synthesis of a key intermediate of a COX-2 inhibitor.

The sulfoximine group proved to be an excellent ortho-directing group in lithiation reactions. Several electrophiles were used to afford the corresponding ortho-functionalized aryl sulfoximines in good yields. The use of prochiral electrophiles lead to mo
