PROCESS FOR THE PRODUCTION OF OPTICALLY ACTIVE CYCLIC ENAMINONE DERIVATIVES

A process for the production of optically active cyclic enaminone derivatives, characterized by aminating one of the carbonyl groups of a cyclic 1,3-diketone derivative having a symmetry plane to thereby obtain an optical isomer mixture of a chiral cyclic enaminone derivative and subjecting this mix...

Abstract A process for the production of optically active cyclic enaminone derivatives, characterized by aminating one of the carbonyl groups of a cyclic 1,3-diketone derivative having a symmetry plane to thereby obtain an optical isomer mixture of a chiral cyclic enaminone derivative and subjecting this mixture to optical resolution. L'invention concerne un procédé de production de dérivés d'énaminone cycliques optiquement actifs, caractérisé par les étapes consistant à : aminer l'un des groupes carbonyle d'un dérivé de 1,3-dicétone cyclique comportant un plan de symétrie pour obtenir un mélange d'isomères optiques contenant un dérivé d'énaminone cyclique chiral ; et soumettre ce mélange à une résolution optique.
