โœฆ Synopsis

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 K 2 CO 3 in DMSO.

A sulfahydantoin (3-oxo-1,2,5-thiadiazolidine 1,1-dioxides) absolute configuration of the chiral centers for the derivative L-Phe-D-Ala, a congener of the series, was established by X-motif is used as a new type of peptidic constraint to lock two consecutive amide nitrogens by a sulfonyl bridge. The
