A new cyclopentene GABA analogue was synthesized as a conformationally rigid analogue of the epilepsy drug vigabatrin. N-Sulfinyl dienophile Diels–Alder methodology, followed by alkaline hydrolysis of the corresponding dihydrothiazine oxide, oxidation and deprotection of the amino group gave cis-4-aminocyclopent-2-ene-1-sulfonic acid. The corresponding N,N-dimethylsulfinamide was also obtained.
