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 N H‐sulfoximines and alkynes (see scheme; Cp*=C 5 Me 5 ). The oxidation system consisted of molecular oxygen in combination with a catalytic amount of Fe(OAc) 2 .
