Oxathiazolone derivatives are commonly used in thermal decarboxylation reactions to generate the corresponding derivative of the short-lived nitrile sulfide which may be trapped by 1,3-dipolar cycloaddition reactions to give heterocycles in low to high yields depending on the nature of the substituent groups.[1]
