  • [EN] NEW PROCESS FOR THE SYNTHESIS OF TAPENTADOL AND INTERMEDIATES THEREOF<br/>[FR] NOUVEAU PROCÉDÉ POUR LA SYNTHÈSE DE TAPENTADOL ET SES INTERMÉDIAIRES
    申请人:ARCHIMICA SRL
    公开号:WO2012001571A1
    公开(公告)日:2012-01-05
    The object of the present invention is a new process for the synthesis of tapentadol, both as free base and in hydrochloride form, which comprises the step of alkylation of the ketone (VII) to yield the compound (VIII), as reported in Diagram 1, with high stereoselectivity due to the presence of the benzyl group as substituent of the amino group. It was surprisingly found that this substitution shifts the keto-enol equilibrium towards the desired enantiomer and amplifies the capacity of the stereocenter present in the compound (VII) to orient the nucleophilic addition of the organometallic compound at the carbonyl towards the desired stereoisomer. This substitution thus allows obtaining a considerable increase of the yields in this step, and consequently allows significantly increasing the overall yield of the entire tapentadol synthesis process. A further object of the present invention is constituted by the tapentadol free base in solid form, obtainable by means of the process of the invention. Still another object of the invention is represented by the crystalline forms I and II of the tapentadol free base. A further object of the present invention is the mixture of the crystalline forms I and II of the tapentadol free base.
    本发明的对象是一种用于合成替本多尔(tapentadol)的新工艺,包括将酮(VII)烷基化以得到化合物(VIII),如图1所示,其具有高立体选择性,这是由于苄基作为氨基的取代基存在。令人惊讶地发现,这种取代将酮-烯醇平衡转向所需的对映体,并增强了化合物(VII)中存在的立体中心引导有机金属化合物在羰基上的亲核加成朝向所需立体异构体的能力。这种取代因此允许在这一步骤中获得产量的显着增加,从而显著提高整个替本多尔合成过程的总产量。本发明的另一个对象是通过本发明的方法获得的固态替本多尔游离碱。本发明的另一个对象是替本多尔游离碱的结晶形式I和II。本发明的另一个对象是替本多尔游离碱的结晶形式I和II的混合物。
