PROCESS FOR THE PRODUCTION OF ENANTIOMERICALLY-PURE AZETIDINE-2-CARBOXYLIC ACID

摘要

The invention relates to a process for the production of enantiomerically-pureAzeOH which comprises selective crystallisation of adiastereomerically-pure tartrate salt thereof, followed by liberation of thefree amino acid, as well as the compounds L-azetidine-2-carboxylicacid-D-tartrate and D-azetidine-2-carboxylic acid-L-tartrate.
