)-1,3-dioxolane). The absolute configuration of etoxadrol hydrochloride, a phencyclidine-like compound biologically, was determined to be 2S, 4S, and 6S at its three chiral centers by single-crystal X-ray analysis. Epietoxadrol (2b), epimeric with etoxadrol at the C-2 center, was also obtained from the synthesis. This much less potent enantiomer has the 2R,4S,6S configuration. The affinity of etoxadrol
由(S,S)-1-(2-哌啶基)合成了Etoxadrol(2a),它是2-乙基-2-苯基-4-(2-哌啶基)-1,3-二氧戊环的8种可能的光学异构体之一)-1,2-乙二醇,它是由右旋沙多醇(1a,(S,S)-2,2-二苯基-4-(2-哌啶基)-1,3-二氧戊环)的裂解获得的。通过单晶X射线分析,确定其在生理学上呈苯环类化合物的艾托沙醇盐酸盐的绝对构型,在其三个手性中心处分别为2S,4S和6S。还从合成中获得了在C-2中心与依托沙醇一起异构的表艾托沙醇(2b)。这种效力低得多的对映异构体具有2R,4S,6S构型。发现埃托沙醇对苯环利定结合位点的亲和力可与苯环利定本身相当,并且其效价为其差向异构体表哌沙他醇的35倍。制备了三种非对映异构体混合物,它们对苯环利定位点的亲和力低。在对这些化合物的区分刺激特性进行的研究中,发现只有艾托沙特能代替苯环利定刺激。通过使用计算机辅助分子建模技术,已经开
