An optical-active cis-piperidine derivative of high chemical purity and high optical purity is efficiently produced through optical resolution of a cis-piperidine derivative mixture, racemic cis-piperidine derivative with an optical-active tartaric acid derivative or an optical-active amino acid derivative. For the optical-active tartaric acid derivative, preferred are optical-active di(paratoluoyl)tartaric acid and optical-active di(4-methoxybenzoyl)tartaric acid; and for the optical-active amino acid derivative, preferred is optical-active N-benzenesulfonylphenylalanine.
通过对顺式哌啶衍生物混合物、外消旋顺式哌啶衍生物与光学活性酒石酸衍生物或光学活性氨基酸衍生物进行光学解析,可高效制得化学纯度和光学纯度都很高的光学活性顺式哌啶衍生物。对于光学活性酒石酸衍生物,优选光学活性二(对羟基苯甲酰基)酒石酸和光学活性二(4-甲氧基苯甲酰基)酒石酸;对于光学活性氨基酸衍生物,优选光学活性 N-苯磺酰基苯丙氨酸。
