proposed for the synthesis of substituted 2-[2-(furan-2-carbonyl)hydrazinylidene]-4-oxobutanoic acids by the reaction of 4-aryl-2,4-dioxobut-2-enoic acids with furan-2-carbohydrazide. It was found that substituted 2-[2-(furan-2-carbonyl)hydrazinylidene]-4-oxobutanoic acids undergo intramolecular cyclization in the presence of propionic anhydride to form the corresponding substituted 2-[2-(furan-2-carbonyl
摘要 提出了一种由4-aryl-2,4-dioxobut-2-enoic酸与furan-2反应合成取代的2-[2-(furan-2-carbonyl)hydrazinylidene]-4-oxobutanoic酸的方法。 -碳酰肼。发现取代的2-[2-(呋喃-2-羰基)亚肼基]-4-氧代丁酸在丙酸酐存在下发生分子内环化形成相应的取代的2-[2-(呋喃-2-羰基)亚肼基]-4-氧代丁酸。对所得化合物的镇痛活性和急性毒性进行了研究,发现所得化合物具有显着的镇痛活性和低毒性。根据药物毒性分类,生成的取代的2-[2-(呋喃-2-羰基)亚肼基]-4-氧代丁酸和2-[5-芳基-2-氧代呋喃-3(2 H)-亚叉基]furan-2-carbohydrazides属于V类几乎无毒的药物。
