IMPROVED PROCESS FOR THE PRODUCTION OF ENANTIOMERICALLY-PURE AZETIDINE-2-CARBOXYLIC ACID |
| 摘要 |
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.
