A simple strategy for the synthesis of the hitherto unreported 3-arylazo-4-phenyl- [1,2,4]triazepino[2,3-a]quinazoline-2,7(1H)-diones is described. Spectral data indicated that the studied compounds exist predominantly in the hydrazone tautomeric form. The antimicrobial activity of the newly synthesized compounds was also evaluated. The results indicated that some of these compounds have moderate activity towards bacteria.
描述了迄今为止未报道的 3-芳基偶氮基-4-苯基-[1,2,4]三氮杂[2,3-a]
喹唑啉-2,7(1H)-二酮的简单合成策略。光谱数据表明所研究的化合物主要以腙互变异构形式存在。还评估了新合成化合物的抗菌活性。结果表明,其中一些化合物对细菌具有中等活性。
