rboxylates with hydrazine hydrate produced hydrazides which were acylated with benzoyl or 2-furoyl chloride and then subjected to heterocyclization to obtain furan derivatives containing a 1,3,4-oxadiazole ring. The target products were also synthesized in one step by reacting 5-aminomethylfuran-2-carbohydrazides with acid chlorides in the presence of phosphoryl chloride.
抽象的 5-氨基甲基呋喃-2-羧酸甲酯与甲胺反应生成5-氨基甲基N-甲基呋喃-2-甲酰胺,其水解得到相应的羧酸。 5-氨基甲基呋喃-2-甲酸甲酯与水合肼反应生成酰肼,用苯甲酰或2-呋喃酰氯酰化,然后进行杂环化,得到含有1,3,4-恶二唑环的呋喃衍生物。在磷酰氯存在下,5-氨甲基呋喃-2-碳酰肼与酰基氯反应一步合成了目标产物。
