Title (EN) METHOD FOR ASYMMETRIC RESOLUTION OF A RACEMIC USING DIPROGULIC ACID AND USE OF SAID ACID AS ASYMMETRIC RESOLUTION AGENT
(FR) PROCEDE DE RESOLUTION ASYMETRIQUE D'UN RACEMIQUE FAISANT INTERVENIR 2,3:4,6-DI-O-ISOPROPYILIDENE-2-KETO-L-GULONIQUE
Abstract: front page image
(EN)The invention concerns a method for resolving a racemic to obtain its optically active isomer characterized in that it consists in reacting, with diprogulic acid or one of its salt, a racemic of general formula (I), wherein: Ar is a heteroaryl group; R1 is an alkyl group; R2 and R3, identical or different, represent each a hydrogen atom or an alkyl group; n is an integer ranging between 0 and 4.
(FR)Procédé de résolution d'un racémique pour l'obtention d'un isomère optiquement actif caractérisé en ce que l'on fait réagir, avec de l'acide diprogulique ou un sel de cet acide, un racémique de formule générale (I) ci-dessous. Dans laquelle, Ar est un groupement hétéroaryl R1 est un groupement alkyl R 2 et R3, identiques ou différents, représentent chacun un atome d'hydrogène ou un groupement alkyl ; n est un entier compris entre 0 et 4.
