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.
分别由硫酰氯与2-氯乙胺或3-氯丙胺盐酸盐反应,分别以高收率合成了烷基和芳基N-取代的1,2,5-噻二唑烷和1,2,6-噻二氮烷1,1-二氧化物6。然后用伯胺和三乙胺处理,并用DMSO中的K 2 CO 3闭环。
