Novel selective [3 + 2] cycloaddition reactions between in situ formed nonstabilized azomethine ylide 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.
