An efficient synthesis of some new octahydroquinazolinone derivatives 4a–x by the cyclocondensation reaction of corresponding 2-thi(oxo)-1,2-dihydroquinoline-3-carbaldehyde 1a–e, 1,3-dicarbonyl compounds 2a–b, and substituted urea 3a–c using zinc triflate as a catalyst in refluxing ethanol in high yield is described. The structures of new compounds have been characterized on the basis of elemental
通过相应的2-thi(oxo)-1,2-dihydroquinoline-3-carbaldehyde 1a - e,1,3-di羰基化合物2a - b和取代的尿素的环缩合反应有效合成一些新的八氢喹唑啉酮衍生物4a - x描述了使用三氟甲磺酸锌作为催化剂以高产率回流乙醇的3a - c。根据元素分析,FT-IR,1 H NMR,13对新化合物的结构进行了表征1 H NMR和质谱数据。评价所有合成的化合物对各种微生物的抗微生物活性。还确定了所有24种合成化合物的最小抑菌浓度值。一些合成的化合物表现出优异的抗微生物活性。
