4-Heterocyclophenyl-substituted dihydropyridines ##STR1## are prepared either by reacting suitable aldehydes with amino esters and .beta.-keto esters, or preparing the heterocyclic substituents of the 4-phenyl by cyclization of corresponding amidines or hydrazides, or esterifying dihydropyridinecarboxylic acids, which are already substituted by heterocyclic radicals, with corresponding alcohols. The 4-heterocyclophenyl-substituted dihydropyridines can be employed in medicaments, in particular for treatment of diseases of the central nervous system.
4-杂环苯基取代的二氢吡啶可以通过将适当的醛与氨基酯和β-酮酯反应,或者通过将4-苯基的杂环取代物的合成方法制备而成,这些合成方法包括通过对应的酰胺或肼基化合物进行环化,或者通过将已经被杂环基团取代的二氢吡啶羧酸与相应的醇酯化。这些4-杂环苯基取代的二氢吡啶可以用于药物中,特别是用于治疗中枢神经系统疾病。
