    摘要:
    描述了新型2-羟甲基-和2-氰基-1, 4-二氢吡啶的合成,这些化合物在其核的5位上具有杂原子取代的烷基酯基团。酯的引入是通过以下方法之一进行的:经过改进的Hantzsch方法(方法A)、通过方法A获得的氯乙酸酯的水解(方法B)或用各种氨基取代氯原子(方法C)。2位的羟甲基和氰基团的制备与之前的文献相似。1)本文中制备的化合物的降压活性与之前报告的在5位的相应烷基酯进行了比较。发现N-苄基甲基氨基乙酯,特别是N-(4-氯苄基)-和N-(3, 4-二氯苄基)-N-甲基氨基乙酯,是1, 4-二氢吡啶核5位上合适的取代基,并且在一系列2-羟甲基-1, 4-二氢吡啶衍生物中,这些取代基的降压活性比简单的烷基酯略强。然而,在一系列2-氰基-1, 4-二氢吡啶衍生物中,效果则相反。两者均被发现不如已经在临床上用于治疗高血压的nilvadipine (1c)。
