pyridine-4-carboxylate which was converted into a number of functional derivatives, including those containing isoxazole and isothiazole heterocycles. In particular, the condensation of the title compound with primary amines afforded the corresponding Schiff bases. 4-Formyl-2-methoxyphenyl pyridine-4-carboxylate and one of the Schiff bases derived therefrom were reduced with sodium triacetoxohydridoborate
将香兰素与异烟酰氯酰化,得到4-甲酰基-2-甲氧基苯基吡啶-4-羧酸酯,将其转化为许多功能性衍生物,包括那些含有异恶唑和异噻唑杂环的衍生物。特别地,标题化合物与伯胺的缩合得到相应的席夫碱。用三乙酰氧基氢硼酸钠将4-甲酰基-2-甲氧基苯基吡啶-4-羧酸酯和其中的一个席夫碱还原为相应的醇和胺,它们分别用5-芳基异恶唑和4,5-二氯异噻唑-3-羰基氯酰化得到具有异恶唑和异噻唑片段的酯和酰胺。合成的化合物易于与氯化钯(II)形成络合物,
