an important anti‐malaria drug that is applied as a racemate of the erythro form. However, the (−)‐isomer induces psychosis, while the (+)‐enantiomer does not have this undesired side effect. There are six syntheses of which five lead to the wrong enantiomer without the authors of these syntheses noting that they had synthesized the wrong compound. At the same time physical chemistry investigations
在这里,我们报告了甲
氟喹的所有四个立体异构体的合成。Mefloquine(Lariam)是一种重要的抗疟疾药物,被用作赤型外消旋体。但是,(-)-对映体会引起精神病,而(+)-对映体不会产生这种不良副作用。有六种合成方法,其中五种导致错误的对映异构体,而这些合成方法的作者并未指出他们合成了错误的化合物。同时,物理
化学研究正确地分配了绝对构型,并且考虑到这些结果的最后对映选择性合成提供了正确的绝对构型。由于各种合成方法都无法在以前的合成中提供正确的立体异构体,
