[EN] A PROCESS FOR PREPARATION OF PHARMACEUTICALLY ACTIVE COMPOUNDS VIA SELECTIVE NITRO REDUCTION REACTIONS [FR] PROCÉDÉ DE PRÉPARATION DE COMPOSÉS PHARMACEUTIQUEMENT ACTIFS PAR RÉACTIONS SÉLECTIVES DE NITRORÉDUCTION
摘要:
The present invention discloses a one-pot process for production of paracetamol frompara-nitrophenol. The present invention discloses preparation of N-(2-amino benzyl)-N-5 methylcyclohexylamine as the intermediate by the nitro-reduction of N-(2-nitrobenzyl)-N-methylcyclohexylamine for production of bromhexine. Further, the present invention also discloses the process for preparingpara-aminophenol (PAP) by the nitro-reduction ofpara-nitrophenol. The invention provides,inter alia, methods for the preparation of compounds using heterogeneous recyclable catalyst. The methods of the present invention are useful for the preparation of a wide array of compounds. The compounds are synthesized rapidly, substantially free of side products and mostly does not require any purification. In particular, the methods of present invention are useful for preparing pharmaceutically active compounds or their intermediates.

revealed excellent catalytic activity to ring‐openingpolymerization (ROP) of LA in the presence of benzyl alcohol. Among them, [L HZnEt] (1) showed the highest activity with 82% conversation within 45 s. In contrast, [L XZn 2(OAc) 3] (6–9) were inactive in ROP of L‐lactide. In addition, all of these Zn complexes demonstrated moderate activity in the reaction of CO2 with cyclohexene oxide in the presence
一系列锌络合物[ L X ZnEt](1-5)和[ L X Zn 2(OAc)3 ](6-9),与NNO三齿Schiff碱配体(2-((((2-合成了(环己基[甲基]氨基)甲基)苯基]亚氨基)甲基)酚盐(CAP)衍生物,它们对L-丙交酯(LA)的开环聚合(ROP )和CO 2与还研究了环己烯氧化物。在苯甲醇存在下,所有[ L X ZnEt]均对LA的开环聚合(ROP)表现出出色的催化活性。其中,[ L H ZnEt](1)在45 s内显示出最高的活性,对话率为82%。相反,[L X Zn 2(OAc)3 ](6–9)在L-丙交酯的ROP中没有活性。另外,所有这些Zn配合物在Bu 4 NCl存在下在CO 2与环己烯的反应中均表现出中等活性。
