O′-di-p-toluoyl-L-tartaric acid and (+)-O,O′-di-p-toluoyl-D-tartaric acid, respectively) as two chiral resolving agents. In contrast to ketamine, the measured specific optical rotation and conformational analysis indicated that the most abundant conformers possess a common axial-methoxyphenyl conformation responsible for the conserved direction of optical rotation in both free base and HCl salt forms
手性分子甲氧西丁(MXE)在治疗难治性抑郁症患者的治疗中显示出有希望的生物学效应。为了满足对能够提供克量的MXE的每个对映体立体异构体以进行对映体的高级生物学研究的方法的需求,开发了一种协议来访问(R)-和(S)-MXE的克级量的MXE形式药学上可接受的盐的HCl采用大号- ( - ) - DTTA和d - (+) - DTTA(( - ) - ö,ö ' -二- p -toluoyl-大号-酒石酸和(+) - ö,ö ' -二对甲苯甲酰基D-酒石酸分别作为两种手性拆分剂。与氯胺酮相反,所测比旋光度和构象分析表明,最丰富的构象异构体具有共同的轴向甲氧基苯基构象,该构型负责以MXE立体异构体的游离碱和HCl盐形式的旋光保守方向。最后,通过匹配实验和计算出的ECD谱图明确分配了绝对构型。本报告提供了获取克级量的对映纯MXE立体异构体的途径,以提高MXE生物学的最新知识。
