CA 2426277

A method including resolution of a diastereomeric mixture represented by the formula (see formula I) wherein R1 and R2 are the same or different and each is an optionally substituted hydrocarbon group or an optionally substituted heterocyclic group, only one of R1 and R2 contains one asymmetric carbon, and R a is an optically active and optionally substituted hydrocarbon group or an optically active and optionally substituted heterocyclic group, or a salt thereof, to produce the diastereomer having a steric configuration of the asymmetric carbon for R1 or R2 of an R configuration or an S configuration, or a salt thereof.

L'invention concerne un procédé de préparation d'un diastéréomère d'un composé représenté par le formule générale (I), dans laquelle l'atome de carbone asymétrique de R?1¿ ou R?2¿ prend une configuration R- ou S-, ou un sel de ce dernier, qui se caractérise par la résolution d'un mélange de diastéréomères du composé ou de leurs sels. (R1) et R?2¿ représentent chacun individuellement un hydrocarbyle éventuellement substitué ou un groupe hétérocyclique éventuellement substitué, pour autant que seul un des R?1¿ et R?2¿ renferme un atome de carbone asymétrique; et R?a¿ est un groupe hydrocarbure qui peut être substitué ou un groupe hétérocyclique optiquement actif pouvant être substitué.
