The present invention relates to a method for the chemical separation of the enantiomers of 1,1′-spirobiindane-6,6′-diol derivatives comprising providing a racemic chiral 1,1′-spirobiindane-6,6′-diol derivative, reacting a nonracemic chiral component with the racemic chiral 1,1′-spirobiindane-6,6′-diol derivative to afford a mixture of diastereomeric diesters, separating the mixture of diastereomeric diesters to provide a substantially pure individual diastereomeric diester, and chemically removing the ester groups from the substantially pure individual diastereomeric diester to provide a nonracemic chiral
1,1
′-spirobiindane-6,6′-diol derivative.
本发明涉及一种化学分离1,1'-螺环二茚-6,6'-二醇衍生物对映体的方法,包括提供一个外消旋手性的1,1'-螺环二茚-6,6'-二醇衍生物,将一个非外消旋手性成分与外消旋手性的1,1'-螺环二茚-6,6'-二醇衍生物反应,得到一种二对映异构二酯混合物,分离该二对映异构二酯混合物以提供一种基本纯净的单个二对映异构二酯,然后从该基本纯净的单个二对映异构二酯中化学去除酯基,得到一个非外消旋手性的1,1'-螺环二茚-6,6'-二醇衍生物。
