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.
从吡咯开始,可以以高达91%ee的效率高效合成新型3,4-二氢吡咯并谷氨酸8或(ent)-8,可用作功能化吡咯烷-2-酮的通用结构单元。此外,(ent)-8可以很容易地转化为(S)-维加巴特林,这是一种不可逆的GABA-T抑制剂,可用于癫痫患者的辅助治疗。
