activity was evaluated against four bacterial strains and one fungal species. Few of the derivatives exhibited antibacterial and antifungal activities. We have reported the synthesis of some thiazolopyrimidine derivatives by cyclo-condensation of dihydropyrimidine with halo esters. Crystal structure analysis of one of the derivatives has been carried out. Some of the derivatives exhibited antibacterial
通过在回流条件下用乙醇处理α-卤代酯与3,4-二氢嘧啶2-硫酮,可制备不同的噻唑并嘧啶取代的二酯,收率71-85%。IR,1 HNMR,13 CNMR和元素分析用于表征这些化合物。用单晶X验证了一种产物5-苯基-3,7-二甲基-5H-噻唑并[3,2-a]嘧啶-2,6-二羧酸二乙酯(3e)的晶体和分子结构。射线衍射法。评价了对四种细菌菌株和一种真菌物种的抗菌活性。很少有衍生物表现出抗菌和抗真菌活性。 我们已经报道了通过二氢嘧啶与卤代酯的环缩合反应合成一些噻唑并嘧啶衍生物。已经对一种衍生物进行了晶体结构分析。一些衍生物表现出抗菌和抗真菌活性。
