A rhodium-catalyzed cyclization reaction of sulfoximines with 3-diazoindolin-2-imines is described. This protocol provides a wide range of indolo-1,2-benzothiazines in moderate to excellent yields together with the release of molecular nitrogen and p-toluenesulfonamide. The present method involves the N–H/C–H activation of S-aryl sulfoximines and has the advantages of a broad substrate scope.
