4-Styryl-1,2,3-benzoxathiazine 2,2-dioxide (4a-e) have been synthesized by the reaction of chlorosulphonyl isocyanate with 2'-hydroxychalcone (1a-e). 2-Hydroxy-1-napthaldehyde reacts with chlorosulphonyl isocyanate to give naphth-oxathiazine 2,2-dioxide (9).The 1,3-dipolar cycloaddition of 1,3-diphenylnitrilimine to 4a-e gives the hitherto unreported heterocyclic system (14)
