The syntheses of four derivatives of gamma-vinyl-GABA, in which vinylic hydrogen atoms were replaced by fluorine, are described. With use of 5-ethenyl-2-pyrrolidinone as starting material, the E and Z isomers of 4-amino-6-fluoro-5-hexenoic acid were prepared. The 6,6-difluoro and 5,6,6-trifluoro analogues could be synthesized from 4-oxobutanoic acid tert-butyl ester and (2,2-difluoroethenyl)- and
描述了γ-乙烯基-GABA的四种衍生物的合成,其中乙烯基氢原子被氟取代。以5-乙烯基-2-吡咯烷酮为原料,制备了4-氨基-6-氟-5-己酸的E和Z异构体。6,6-二氟和5,6,6-三氟类似物可以分别由4-氧代丁酸叔丁酯和(2,2-二氟乙烯基)-和(三氟乙烯基)锂合成。测试了这些化合物作为GABA-T的抑制剂,并报道了其体外和体内生物化学。活性最高的衍生物是(Z)-4-氨基-6-氟-5-己酸。讨论了该系列中的构效关系。
