Title
(EN) NOVEL METHOD FOR PREPARING CHIRAL AMINO ACIDS
(FR) NOUVEAU PROCEDE DE PREPARATION D'AMINOACIDES CHIRAUX
Abstract
(EN)
The invention concerns a novel method for preparing chiral amino acids of formula (I) characterised in that it consists in contacting a racemic hydantoin of formula (II) with an enantiomeric splitting agent.
(FR)
Nouveau procédé de préparation d'aminoacides chiraux de formule (I) caractérisé en ce que l'on met en contact une hydantoïne racémique de formule (II) avec un agent de dédoublement énantiomérique.
