straight forward synthesis of the 1,4,2-benzodithiazine system bearing an ester functionality as potential inducers of systemic acquired resistance in plants was developed utilizing the ringexpansionreaction of 1,3-benzodithioles. The structure of the isomers obtained was established using x-ray diffraction. The reactivity of the products towards activated alkynes and ring contraction reactions in the presence
