Process for obtaining enantiomers of 2-arylpropionic acids
A process for obtaining enantiomers of 2-arylpropionic acids by reacting a racemic mixture thereof with an amine-enantiomer, which process comprises converting the racemate of the 2-arylpropionic acid with an optically active form of threo-1-p-nitrophenyl-2-aminopropane-1,3-diol into the diastereome...

| Zusammenfassung: | A process for obtaining enantiomers of 2-arylpropionic acids by reacting a racemic mixture thereof with an amine-enantiomer, which process comprises converting the racemate of the 2-arylpropionic acid with an optically active form of threo-1-p-nitrophenyl-2-aminopropane-1,3-diol into the diastereomeric salts, separating these salts and converting the thus-obtained pure diastereomers into the free acids of the enantiomer forms of the 2-arylpropionic acid or into the salts thereof. |
