A process for resolving a compound in racemic form comprising the following steps is described: a) reacting a compound in racemic form with a resolving agent, b) forming a diastereoisomeric complex of the resolving agent and an enantiomer of interest, c) separating the enantiomer of interest from the obtained diastereoisomer, wherein such a process is characterized in that said resolving agent is a compound of Formula (I). A diastereoisomeric complex between the resolving agent of Formula (I) and the enantiomer of interest is also described. The process according to the invention allows acid and basic racemic mixtures to be separated.
本发明提供了一种用于分离外消旋化合物的方法,包括以下步骤:a)将外消旋化合物与分离剂反应,b)形成分离剂和所需对映体的非对映异构体复合物,c)从所得的非对映异构体中分离所需对映体。其中,所述分离剂为式(I)的化合物。本发明还描述了分离剂式(I)与所需对映体之间的非对映异构体复合物。本发明所述方法可以分离酸性和碱性外消旋混合物。
