Revitalization by oxygen: A rhodium(III)-catalyzed oxidative CH/NH activation/annulation sequence provided access to a variety of substituted 1,2-benzothiazine derivatives from readily available NH-sulfoximines and alkynes (see scheme; Cp*=C5Me5). The oxidation system consisted of molecular oxygen in combination with a catalytic amount of Fe(OAc)2.
