The present specification relates to a chiral resolution method of a stereoisomer mixture, comprising a step of mixing a stereoisomer mixture of compounds, in which an amine group is bound to an asymmetric carbon atom, with a chiral auxiliary and salt-forming auxiliary compound, wherein the chiral auxiliary is an O,O′-diacyltartaric acid derivative, more specifically, a 2,3-dibenzoyl-tartaric acid or O,O′-di-p-toluoyl tartaric acid, the salt-forming auxiliary compound is mandelic acid or camphorsulfonic acid, and an optical isomer having a high level of optical purity can be obtained by using the method. Therefore, according to one aspect of the present invention, the method can be useful in pharmaceutical or cosmetic field when preparing an optical isomer having a high optical purity.
本规范涉及一种手性分离方法,包括以下步骤:将含有胺基与不对称碳原子结合的化合物的立体异构物混合物与手性辅助剂和盐形成辅助剂混合,其中手性辅助剂是O,O′-二酰基酒石酸衍生物,更具体地说是2,3-二苯乙酰酒石酸或O,O′-二对甲苯酰酒石酸,盐形成辅助剂是苯甲酸或藿香磺酸,通过使用该方法可以获得具有高光学纯度的光学异构体。因此,根据本发明的一个方面,在制备具有高光学纯度的光学异构体时,该方法在制药或化妆品领域中可能是有用的。
