Improved process for the production of enantiomerically-pure azetidine-2-carboxylic acid |
| abstract |
The invention relates to a process for the production of enantiomerically-pure AzeOH which comprises selective crystallisation of a diastereomerically-pure AzeOH-tartrate salt from a homogeneous solution of AzeOH, optically-active tartaric acid, an organic acid and an aldehyde, followed by liberation of the free amino acid. |
