The cis and trans enantiomers of the 1-(1-methylcyclohexyl)piperidines were prepared from either 3(R)- or 3(S)-methylcyclohexanone through the Bruylents reaction or a modified azide route, respectively. Separation of the intermediate amines 5 and 6 was achieved through chromatography or selective crystallization of a fumarate salt. The cis isomer 2b had about one-third of the affinity of phencyclidine
1-(1-甲基环己基)哌啶的顺式和反式对映体分别通过Bruylents反应或修饰的叠氮化物路线由3(R)-或3(S)-甲基环己酮制备。中间体胺5和6的分离是通过色谱法或富马酸盐的选择性结晶实现的。顺式异构体2b具有苯环利定对PCP受体的亲和力的约三分之一。其他异构体的效力较弱。顺式对映异构体2a和2b的结合亲和力之间有40倍的差异,反式对映异构体1a和1b的亲和力之间有4倍的差异。腹膜内引入后,没有一种化合物能拮抗苯环利定在小鼠转子试验中的定型作用。
