Abstract

Des cis- et trans-pyrrolopipéridines sont séparées de manière avantageuse en leurs isomères optiques lorsque l'on monoacyle par voie enzymatique un mélange contenant de la (R,R)- et (S,S)-pyrrolopipéridine ou bien de la (S,R)- et (R,S)-pyrrolopipéridine. On obtient alors un mélange (I) contenant de la (R,R)- et (S,S)-6-acyl-pyrrolopipéridine ou bien de la (S,R)- et (R,S)-6-acyl-pyrrolopipéridine, on acyle à nouveau par voie enzymatique ce mélange (I), on obtient alors un mélange (II) contenant de la (S,S)-1,6-diacyl- et (R,R)-6-acyl-pyrrolopipéridine ou bien de la (S,R)-1,6-diacyl- et (R,S)-6-acyl-pyrrolopipéridine, on sépare du mélange (II) l'enzyme et éventuellement le solvant et l'agent d'acylation en excès, on traite le reste avec un acide aqueux et on sépare par extraction la (S,S)-1,6-diacyl-pyrrolopipéridine ou bien la (S,R)-1,6-diacyl-pyrrolopipéridine et on alcalinise le résidu de l'extraction, et on sépare par extraction la (R,R)-6-acyl-pyrrolopipéridine ou bien la (R,S)-6-acyl-pyrrolopipéridine. A partir des dérivés acylés exempts d'isomères, on peut éventuellement préparer la base libre selon les méthodes habituelles de la séparation des groupes acylés.
