oxazolones 2a-c in presence of drops of acetic acid under fused condition yielding the imidazolone derivatives 6-13. Furthermore, Schiff base of compounds 14-16 were obtained by condensing 5, 6-diaminouracils 1a,b,e with 4-dimethylaminobenzaldehyde in acetic acid. The structural identity of the resulting compounds was resolved by IR, 1H-, 13C-NMR and Mass spectral analyses. The novel synthesized compounds
以恶唑酮衍生物2a-c为关键中间体,合成了新型黄嘌呤和咪唑酮衍生物。恶唑酮衍生物2a-c与5,6-二氨基尿嘧啶1a-e在不同条件下反应得到相应的黄嘌呤3-5和咪唑酮衍生物6-13 。黄嘌呤化合物3-5是通过5,6-二氨基尿嘧啶1a-c与不同恶唑酮在冰醋酸中环缩合得到的。此外,5, 6-二氨基尿嘧啶1a-e与恶唑酮2a-c在乙酸滴的存在下在熔融条件下反应,产生咪唑酮衍生物6-13 。此外,通过将5, 6-二氨基尿嘧啶1a,b,e与4-二甲氨基苯甲醛在乙酸中缩合,得到化合物14-16的席夫碱。通过IR、 1 H-、 13 C-NMR 和质谱分析解析所得化合物的结构特性。筛选了新合成的化合物的抗真菌和抗菌活性。从 IC 50值 ( 1.8–1.9 µg/mL)可以看出,化合物3、6、13和16对大肠杆菌表现出最高的活性。与真正的抗生素相比,化合物16对白色念珠菌(0.82 µg/mL)、黄曲霉(1
