The synthesis of some substituted 7-hydroxy-5H-1,3,4-oxadiazolo [3,2-a]pyrimidin-5-ones, a class of bicyclics with unexplored pharmacotoxicological properties, is described. Reacting the 2-phenyl derivative with bis(2,4,5-trichlorophenyl)benzylmalonate afforded a linear pyrano-oxadiazolopyrimidinedione. The assigned structures were verified by IR, 1H-NMR, and mass spectral studies. Six compounds of
描述了一些取代的7-羟基-5H-1,3,4-恶二唑并[3,2-a]嘧啶-5-酮的合成,这是一类未经开发的药理毒理学性质的双环化合物。使2-苯基衍生物与丙二酸双(2,4,5-三氯苯基)苄基酯反应,得到线性吡喃-恶二唑并嘧啶二酮。通过IR,1 H-NMR和质谱研究验证了指定的结构。筛选了该系列的六个化合物的体外抗菌和抗真菌活性。还检查了四种化合物对碱性磷酸酶的影响。
