## Abstract magnified image By reacting 4,5βunsubstituted isothiazole dioxides with diazoalkanes and nitrile oxides bicyclic pyrazolo[3,4β__d__]isothiazole and isothiazolo[5,4β__d__]isoxazole __S,S__βdioxides were obtained in good yield through a regioselective cycloaddition reaction. Through cycl
## Abstract The ^13^C NMR spectra of four thiocarbamates and their corresponding __S__βoxides and __S__, __S__βdioxides are reported. Both Ξ²~SO~ and Ξ² effects are deshielding and range from 20.44 to 21.68 ppm. The Ξ²~SO~β² effects are slightly deshielding (0.20 βΌ 0.0.77 ppm). The Ξ²β² effects, on the c
