Abstract
Alkyl and aryl N-substituted 1, 2, 5-thiadiazolidine and 1, 2, 6-thiadiazinane 1, 1-dioxides 6 were synthesized in good yields from the reaction of sulfuryl chloride with 2- chloroethylamine or 3-chloropropylamine hydrochlorides, respectively, followed by treatment with a primary amine and triethylamine, and ring closure with K2CO3 in DMSO.
