Abstract
制备1,4-二氢吡啶化合物的方法,包括烯胺化合物和具有如右下式结构的化合物在碱存在下接触;并在酸或酸的组合存在下,在温和的反应条件下处理所得的反应混合物。产生的1,4-二氢吡啶化合物被用作消炎药等等。
Description
本发明涉及制备1,4-二氢吡啶化合物的方法。具有1,4-二氢吡啶结构的化合物广泛地用于制药业。该化合物已经被用于,例如,治疗或预防诸如心血管病或炎症的疾病。
硝苯吡啶和氨氯地平是公知的作为钙通道阻断剂的1,4-二氢吡啶化合物。
最近,已经发现某些1,4-二氢吡啶化合物具有缓激肽拮抗活性。例如,PCT国际专利申请WO96/06082和WO97/30048,和美国专利5861402公开了具有缓激肽拮抗活性的1,4-二氢吡啶化合物,它可用于治疗包括炎症,心血管疾病和产生疼痛的创伤的疾病或综合征。这些缓激肽拮抗化合物的特征在于,在其2-位带有包括诸如羰基,酯,酰胺或亚酰胺部分的取代基。
各种1,4-二氢吡啶制备方法已经被公开。例如,Hantzsch合成已经广泛地用作1,4-二氢-2,6-二甲基吡啶的制备方法。该方法可以通过两摩尔β-二碳酸酯与一摩尔醛在氨存在下缩合而进行。J.B.Sainani报道了在其3-和5-位具有不对称取代基的1,4-二氢-2,6-二甲基吡啶化合物的合成(包括药物化学的有机化学Org.Chem.Incl.Med.Chem.(1994),33b(6),573-575)。
本发明也提供制备式(Ⅰ)化合物的方法:其中:R1选自氢和(C1-C4)烷基;R2选自腈;-SO3H;-SO2-(C1-C6)烷基;-SO-(C1-C6)烷基;-PO[O(C1-C4)烷基]2;-C(=O)-R7,其中R7选自羟基或其盐,(C1-C6)烷基-O-,氨基,(C1-C6)烷基-NH-和二[(C1-C6)烷基]-N-;R3和R5独立地选自腈和(C1-C5)烷氧基-C(=O)-;R4是未取代或一-,二-,三-,四-或五-取代的苯基,其中取代基独立地选自卤原子;任选地被一至三个卤原子取代的(C1-C4)烷基;任选地被一至三个卤原子取代的(C1-C4)烷氧基;硝基;氨基;一(C1-C4)烷基氨基和二[(C1-C4)烷基]氨基;R6选自氢;(C1-C10)烷基;任选地被一至二个独立地选自卤原子,(C1-C4)烷基,三-卤(C1-C4)烷基和(C1-C4)烷氧基的取代基取代的苯基;和含有1至4个杂原子或独立地选自-O-,-S-,-NH-和-N[(C1-C4)烷基]-的含有杂原子的部分的4-至10-员杂环,其中所说的杂环是饱和的,部分-饱和的或芳香性的,并且所说的杂环任选地被一个卤原子或(C1-C4)烷基取代;和Y选自共价键,亚甲基,氧和硫;该方法包括如下步骤(a)下式的烯胺化合物与下式的化合物其中R1,R2,R3,R4,R5,R6和Y如前定义,在碱存在下,在足以偶合化合物的条件下加成反应;和(b)使步骤(a)产生的化合物在选自质子酸,和质子酸(protonic acid)与非质子Lewis酸组合的酸催化剂存在下环化。
在上述方法中,其中R2是羧基的盐的式(Ⅰ)或(Ⅱ)化合物(即,R2是其中R7是羟基盐的-C(=O)-R7)是羧酸的无机或有机盐。这些盐用诸如碱金属或碱土金属(例如,钠,钾,钙,和镁),氢氧化物或醇盐的阳离子在水或适当的有机溶剂如乙醇,异丙醇或其混合物中形成。
根据本发明,一般说来,所需的1,4-二氢吡啶化合物可以在温和的条件下,在一锅合成中以高产率制备。
在上述方法中,优选的式(Ⅱ)底物和产生的式(Ⅰ)化合物是其中R1是氢的各式化合物。
