The invention is directed to optically active proline derivative of the general formula: ##STR1## in which X is a hydrogen atom or a hydroxyl group and R is a hydrogen atom, an unsubstituted or alkyl group substituted phenyl group or a straight chain or branched alkyl group having 1 to 20 carbon atoms and a process for its production by reacting an enantiomerically pure proline or 4-hydroxy-proline as a solution in an alkanol having 1 to 4 carbon atoms with 0.9 to 2 times the molar amount of an alkali metal alcoholate corresponding to the alkanol and 1 to 3 times the molar amount of an epoxide of the general formula ##STR2## in which R is as defined above. The optically active proline derivative of general formula (I) can be used in the form of metal ion chelate complexes as the chiral stationary phase in the separation of enantiomers by means of liquid chromatography.
该发明涉及一种具有一般式的光学活性脯氨酸衍生物:##STR1##其中X是氢原子或羟基,R是氢原子、未取代或取代的烷基苯基或具有1至20个碳原子的直链或支链烷基。通过将外消旋纯脯氨酸或4-羟基脯氨酸溶液与相当于醇类有1至4个碳原子的碱金属醇盐的摩尔量的0.9到2倍和一般式的环氧化物的摩尔量的1到3倍在反应中生产。其中R如上所定义。一般式(I)的光学活性脯氨酸衍生物可以作为金属离子螯合物的形式,用于通过液相色谱分离对映体的手性固定相。
