1,2,5‐Thiadiazolidine‐1,1‐dioxide carboxamide derivatives 3a‐3n are novel heterocyclic compounds synthesized by multicomponent condensation reaction in one pot of aniline, chlorosulfonyl isocyanate, and 2‐chloroethylamine hydrochloride which is used as a useful precursor under mild conditions. This reaction is realized with high atom economy, at room temperature and in a short reaction time. Series of these desired products are obtained from good to excellent yields within 2 hours in all cases. All the synthesized compounds are characterized by 1 H, 13 C NMR, MS, and HMBC/HSQC spectroscopy.
