Synthesis of functionalized pyrrolidin-2-ones and (S)-Vigabatrin from pyrrole.
Starting from pyrrole, the novel 3,4-didehydropyrohomoglutamate 8 or (ent)-8 can be efficiently synthesized in up to 91% ee, which can be utilized as a versatile building block toward functionalized pyrrolidin-2-ones. Moreover, (ent)-8 can be readily converted to (S)-Vigabatrin, being an irreversible inhibitor for GABA-T, which is used as adjunctive therapy in patients that suffer from epilepsy.
