Pirlindole is an antidepressant drug. It acts principally as reversible inhibitor of monoamine oxidase-A (RIMA) and appears relatively potent in comparison with reference drugs. Pirlindole possesses stereogenic center but is generally used as racemate. In this work, the first preparative resolution of its enantiomeric couple is described. Whereas selective crystallization of salts of chiral acid failed
吡咯啉是抗抑郁药。它主要用作单胺氧化酶-A(RIMA)的可逆抑制剂,并且与参考药物相比显得相对有效。吡咯啉具有立体定向中心,但通常用作外消旋体。在这项工作中,描述了其对映异构体对的第一个制备性拆分。尽管手性盐的选择性结晶失败了,但还研究了两个不对称合成途径;但是,没有成功。最后,通过衍生化方法与制备型HPLC结合,完成了吡咯烷对映体的分离和分离。通过手性HPLC测定每种异构体的光学纯度。还确定了每种对映体的比旋光度。
