The enantiomers of 9-hydroxyrisperidone, the major metabolite of risperidone and the active component of the
antipsychotic drug Invega®, were synthesized by efficient methods. Their optical rotation and enantiomeric purity were
characterized for the first time. The absolute configurations were assigned by comparing 1H NMR chemical shifts of
Mosher esters of a key stereoisomeric intermediate. Thus, the stereoisomeric center of (+)-9-hydroxyrisperidone has been
assigned as the S configuration, and its enantiomer has the configuration R.
9-羟基利培酮的对映体是利培酮的主要代谢产物,也是抗精神病药物Invega®的活性成分,采用高效方法合成。首次对其光旋转和对映体纯度进行了表征。通过比较关键立体异构中间体的Mosher酯的1H NMR化学位移,确定了绝对构型。因此,(+)-9-羟基利培酮的立体异构中心被指派为S构型,其对映体则为R构型。
