  • METHOD FOR PRODUCING NEBIVOLOL
    申请人:Jas Gerhard
    公开号:US20130005001A1
    公开(公告)日:2013-01-03
    The present invention relates to a method for producing racemic nebivolol represented by general formula (I) from the enantiomerically-pure compounds represented by formula (IVa) and (IVb); whereby racemic nebivolol is obtained through mixing enantiomerically-pure d-nebivolol and l-nebivolol which are synthesised independent of each other as enantiomerically-pure compounds through individual coupling of the 4 enantiomerically-pure key intermediates represented by formula (IIa-d) to the corresponding precursors represented by formula (IIIa-d); whereby d-nebivolol (Ia) is obtained through coupling (IIa) to (IIIb) or (IIb) to (IIIa) and l-nebivolol (Ib) is obtained through coupling (IIc) to (IIId) or (IId) to (IIIc), and PG in the intermediates represented by formula (IIa-d) is a hydrogen atom or an amine protection group, and X in the precursors represented by formula (IIIa-d) is a halogen atom, a hydroxyl group, an acyl group, an alkylsulfonyloxy group or an arylsulfonyloxy group, whereby intermediate (IIa) is formed from (IIIa), intermediate (IIb) is formed from (IIIb), intermediate (IIc) is formed from (IIIc), and intermediate (IId) is formed from (IIId), whereby the precursors represented by formula (IIIa) and (IIId) originate from the ketone precursor represented by formula (IVa), and the precursors represented by formula (IIIb) and (IIIc) originate from the ketone precursor represented by formula (IVb), and Z in the ketone precursors (IVa,b) is a halogen atom, a hydroxyl function, an acyl group, an alkylsulfonyloxy group or an arylsulfonyloxy group.
    本发明涉及一种从化学式(IVa)和(IVb)所代表的对映纯化合物中生产化学式(I)所代表的混合型尼倍洛尔的方法;通过将化学式(IIa-d)所代表的4个对映纯中间体与化学式(IIIa-d)所代表的相应前体进行个体的偶联,将对映纯d-尼倍洛尔和l-尼倍洛尔合成为对映纯化合物,从而获得混合型尼倍洛尔。其中,通过将(IIa)与(IIIb)或(IIb)与(IIIa)偶联可得到d-尼倍洛尔(Ia),通过将(IIc)与(IIId)或(IId)与(IIIc)偶联可得到l-尼倍洛尔(Ib)。在化学式(IIa-d)所代表的中间体中,PG为氢原子或胺保护基,在化学式(IIIa-d)所代表的前体中,X为卤原子、羟基、酰基、烷基磺酰氧基或芳基磺酰氧基。其中,中间体(IIa)由(IIIa)形成,中间体(IIb)由(IIIb)形成,中间体(IIc)由(IIIc)形成,中间体(IId)由(IIId)形成。化学式(IIIa)和(IIId)所代表的前体源自化学式(IVa)所代表的酮前体,化学式(IIIb)和(IIIc)所代表的前体源自化学式(IVb)所代表的酮前体。化学式(IVa,b)中的Z为卤原子、羟基、酰基、烷基磺酰氧基或芳基磺酰氧基。
