The regiospecific synthesis of chiral N-acyl cyclosulfamides (sulfa-analogues of cyclic ureas) was carried out starting from chlorosulfonyl isocyanate (CSI), 1-substituted N-benzyl-2-chloroethylamine hydrochloride and acyl chloride. Chiral N-acyl-thiadiazolidines 1,1-dioxides have been prepared in high yield starting from the corresponding cyclosulfamides acyl chloride, triethylamine and a catalytic amount of 4-(N,N-dimethylamino)pyridine.
