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 tartrate salt thereof, followed by liberation of the free amino acid, as well as the compounds L-azetidine-2-carboxylic acid-D-tartrate and D-azetidine-2-ca0072boxylic acid-L-tartrate.
