Abstract

PROCEDE DE MONOESTERIFICATION DE DIACIDES DE PYRROLE SUBSTITUES EN UTILISANT COMME CATALYSEUR D'ESTERIFICATION UNE RESINE D'ECHANGE D'IONS FORTEMENT ACIDE. EN UTILISANT UNE RESINE D'ECHANGE DE CATIONS A LA PLACE D'UN ACIDE MINERAL CLASSIQUE POUR CATALYSER LA REACTION ENTRE LES DIACIDES DE PYRROLE SUBSTITUES ET LES ALCANOLS ANHYDRES UTILISES COMME AGENTS D'ESTERIFICATION, IL EST POSSIBLE D'OBTENIR UN ACIDE-ESTER DE PYRROLE SUBSTITUE DONT UN GROUPEMENT ACIDE ACETIQUE EST SELECTIVEMENT ESTERIFIE EN POSITION 2 DU NOYAU PYRROLE. LES COMPOSES OBTENUS PERMETTENT DE PREPARER DES PYRROLE-2-ACETATES A SUBSTITUANTS ALKYLE ET AROYLE, QUI SONT DES AGENTS ANTI-INFLAMMATOIRES.
