piperazine-1-carboxylate (1) by several steps. The treatment of amine, 3 or hydrazide, 9 with several aromatic aldehydes generated the corresponding arylmethyleneamino (3a–f) or arylidenehydrazino (12a–c) compounds. The Mannich reaction between the 1,2,4-triazole or 1,3,4-oxadiazole compounds and 7-aca produced cephalosporanic acid derivatives. Penicillanic acid derivatives were obtained when 6-apa was used in the
乙基 4-amino-2-fluorophenylpiperazin-1-carboxylates 含有 1,3-oxazol(idin)e, 5-thioxo-1,2,4-triazole, 1,3,4-thiadiazole, 5-thioxo-1, 3,4-恶二唑或1,3-噻唑核是从哌嗪-1-羧酸乙酯( 1 )开始通过几个步骤获得的。胺, 3或酰肼, 9用几种芳香醛处理产生相应的芳基亚甲基氨基( 3a – f ) 或亚芳基肼基( 12a – c) 化合物。1,2,4-三唑或1,3,4-恶二唑化合物与7-aca 之间的曼尼希反应产生头孢烷酸衍生物。当在曼尼希反应中使用 6-apa 时得到青霉酸衍生物。对合成的化合物进行了抗微生物、抗脂肪酶和抗脲酶活性的筛选。发现其中一些对测试微生物具有良好的中等抗微生物活性。两种化合物表现出抗脲酶活性,其中四种表现出抗脂肪酶活性。
