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. Key Words: Hetero Diels-Alder reactions / Regioselectivity / Ring contraction / Molecular dynamics

Benzothiete (1) undergoes cycloaddition reactions with hetero dienophiles with NN-, NO- or CO- double bonds, leading to six-membered heterocyclic ring systems of 2H-3,4-dihydro-1,2,3-benzothiadiazine (3), 4H-3,1,2-benzoxathiazine (4) and 4H-3,1-benzoxathiin.
