    DOI:10.1016/j.tet.2007.03.146
    日期:2007.6
    Reaction of N-vinylic phosphazenes with α,β-unsaturated ketones leads to the formation of pyridines derived from β-amino acids in a regioselective fashion. The use of functionalized enones derived from α-acylstyryl-carboxylates or -phosphonates affords biologically active asymmetrical and symmetrical dihydropyridines substituted with carboxylate or phosphonate groups including nitrendipine, felodipine

  • [EN] PROCESS FOR THE PREPARATION OF 4 -SUBSTITUTED -1, 4-DIHYDROPYRIDINES<br/>[FR] PROCÉDÉ POUR LA PRÉPARATION DE 1,4-DIHYDROPYRIDINES SUBSTITUÉES EN POSITION 4
    申请人:ARCH PHARMALABS LTD
    公开号:WO2012123966A1
    公开(公告)日:2012-09-20
    4-Substituted-l,4-dihydropyridines of formula I are prepared by a cycloaddition reaction in which the cyclization is driven to completion at ambient temperature optionally in water without any catalyst. For exemplary purposes, the invention is described in particular detail with respect to the preparation of felodipine of formula II. Felodipine, a vasodilator, is prepared by a cycloaddition reaction of alkyl 3- aminocrotonate with dichlorobenzylidene under reaction conditions whereby the product crystallizes out of the reaction solution and may be directly isolated by filtration.
    通过环加成反应制备公式I的4-取代-1,4-二氢吡啶,该环化反应在室温下可在水中无需任何催化剂的情况下完全进行。为了举例说明,本发明特别详细地描述了制备公式II的非洛地平的方法。非洛地平是一种血管扩张剂,通过烷基3-氨基丙烯酸酯与二氯苯甲醛进行环加成反应制备,反应条件下产物结晶出来并可通过过滤直接分离。
