  • METHODS FOR THE PREPARATION OF TAXANES USING CHIRAL AUXILIARIES

    The present invention relates to a stereoselective synthesis of novel β-lactam dimers as useful precursors for the preparation of paclitaxel, docetaxel, and analogues thereof. More particularly, the new β-lactams are prepared from readily available and enantiomerically pure chiral auxiliaries. The β-lactams are then reacted with a suitably protected taxane to produce diastereomerically enriched side chain-bearing taxanes. Finally, the chiral auxiliary is cleaved and protecting groups are removed to provide the desired taxane.
    本发明涉及一种立体选择性合成新型β-内酰胺二聚体作为紫杉醇、多西他赛及其类似物制备的有用前体。更具体地说,新的β-内酰胺从易得到的对映纯手性助剂制备而来。然后,β-内酰胺与适当保护的紫杉烷类反应,产生具有立体异构富集的侧链含有紫杉烷类物质。最后,手性助剂被裂解,保护基被去除,提供所需的紫杉烷类物质。

    [EN] The present invention relates to a stereoselective synthesis of novel ß-lactam dimers as useful precursors for the preparation of paclitaxel, docetaxel, and analogues thereof. More particularly, the new ß-lactams are prepared from readily available and enantiomerically pure chiral auxiliaries. The ß-lactams are then reacted with a suitably protected taxane to produce diastereomerically enriched side chain-bearing taxanes. Finally, the chiral auxiliary is cleaved and protecting groups are removed to provide the desired taxane.
    [FR] L'invention concerne une synthèse stéréosélective de dimères de ß-lactams utilisés comme précurseurs utiles pour la préparation de paclitaxel, de docétaxel et des analogues de ceux-ci. Plus précisément, les ß-lactams sont préparés à partir d'auxiliaires chiraux facilement disponibles et purs sur le plan énantiomérique. Les ß-lactams sont ensuite mis à réagir avec un taxane protégé de manière appropriée, aux fins de production de taxanes porteurs de chaînes latérales enrichis sur le plan diastéréomère. Puis, l'auxiliaire chiral est clivé et des groupes de protection sont retirés de manière à obtenir le taxane souhaité.
