Syntheses of the 4-methyl (2 and 3) and [3.2.1]bicyclo (4 and 5) analogues of the glycine/N-methyl-D-aspartate (NMDA) antagonist 3-amino-1-hydroxypyrrolidin-2-one (HA-966, 1) provide evidence that glycine receptor recogntion requires the energetically less favoured 3-pseudoaxial conformation of the pyrrolidone ring, resulting in a 5–10 fold improvement in activity with the 3R-amino, 4R-methyl derivative
甘氨酸/ N-甲基-D-天门冬氨酸(NMDA)拮抗剂3-氨基-1-羟基吡咯烷-2-酮的4-甲基(2和3)和[3.2.1]双环(4和5)类似物的合成(HA-966,1)提供的证据表明甘氨酸受体recogntion要求吡咯烷酮环的能量少青睐3- pseudoaxial构象,导致5-10倍的提高的活性与3 - [R -氨基,4 - [R -甲基衍生物(2a,L-687414)。
