Cycloaddition Reactions of Benzothiete and Aromatic Nitroso Compounds The new heterocyclic ring systems 4H‐3,1,2‐benzoxathiazines 4 and 2,3‐dihydro‐1,2‐benzothiazol 1‐oxides 6 can be synthesized by cycloaddition of benzothiete ( 1 ) and aromatic nitroso compounds 3 . The regioselectivity of the primary step and the secondary thermal or acid‐catalyzed rearrangements are discussed.
