Some new N-(4-chlorophenyl)-6-methyl-4-aryl-2-thioxo-1,2,3,4-tetrahydro pyrimidine-5-carboxamide 4(a–h) were synthesized by the reaction of N-(4-chlorophenyl)-3-oxobutanamide, thiourea and different aromatic aldehydes. The synthesis of N-(4-chlorophenyl)-7-methyl-5-aryl-2,3-dihydro-5H-thiazolol[3,2-a]pyrimidine-6-carboxamide 5(a–h) was accomplished by cyclocondensation of 1,2,3,4-tetrahydropyrimidine-2-thiones
通过N-反应合成了一些新的N-(4-氯苯基)-6-甲基-4-芳基-2-硫代-1,2,3,4-四氢嘧啶-5-甲酰胺4(a-h) (4-氯苯基)-3-氧代丁酰胺、硫脲和不同的芳香醛。N-(4-氯苯基)-7-甲基-5-芳基-2,3-二氢-5H-噻唑醇[3,2-a]嘧啶-6-甲酰胺5(a-h)的合成是通过环缩合反应完成的1,2,3,4-四氢嘧啶-2-硫酮 4(a-h) 和 1,2-二溴乙烷。这些化合物的结构已通过 IR、1H-NMR 和质谱研究证实。对合成的化合物 4(a-h) 和 5(a-h) 的抗菌活性进行了评估。与标准药物相比,一些化合物表现出对细菌和真菌生长的显着抑制。
