A PROCESS FOR THE PREPARATION OF (-)-ESERETHOLE FROM MIXTURES OF (-) AND (+)-ESERETHOLE
A process for the preparation of (-)-eserethole, of formula (I) starting fro m (~)-eserethole, or from mixtures of (+)-and (-)-eserethole in which the latter enantiomer prevails by treating (~)- eserethole or mixtures of (~)- and (-)-eserethole enriched in the latter enantiomer, with 0.5-0.7 mole (p...

| description | A process for the preparation of (-)-eserethole, of formula (I) starting fro m (~)-eserethole, or from mixtures of (+)-and (-)-eserethole in which the latter enantiomer prevails by treating (~)- eserethole or mixtures of (~)- and (-)-eserethole enriched in the latter enantiomer, with 0.5-0.7 mole (per mole of the enantiomeric mixture) of a resolution agent, to yield a (-)-eserethole salt less soluble than the corresponding (+)-eserethole salt. |
