Derivatives of isothiazol-3(2H)-one 1,1-dioxide react regiospecifically with 1,3-dipolar agents. The main regiocontrolling factor is ascertained to be the CO group of the dipolarophile. The topology of the adducts is also in general agreement with predictions based on perturbation theory. Several adducts can be aromatized to heterocyclic equivalents of saccharin, and may then be elaborated into structural

Novel selective [3 + 2] cycloaddition reactions between in situ formed nonstabilized azomethineylide generated from N-benzyl-1-methoxy-N-((trimethylsilyl)methyl)methanamine enabled by Lewis acids and bioactive molecules isothiazol-3(2H)-ones have been developed. The reaction selectively afforded novel thiazolidines or cyclo-fused oxazolidinones depending on Lewis acid catalyst system of reaction used
