assisted method is preferable because of the time reduction and yield improvements achieved. The new compounds were tested for their biological activity as antioxidants, antibacterial or antifungal agents. Some of the new compounds were found to have moderate to good antioxidant and antimicrobial activities.
乙酰乙酸乙酯、硫脲和适当的芳香醛的 Biginelli 反应用于生产 4-aryl-6-methyl-2-thioxo-1,2,3,4-tetrahydro-pyrimidine-5-carboxylates,它与溴丙二腈反应生成得到 3-氨基-5-芳基-2-氰基-7-甲基-5H-噻唑并[3,2-a]嘧啶-6-羧酸乙酯,而不是异构的7H-噻唑并[3,2-a]嘧啶。噻唑并嘧啶衍生物与二硫化碳反应生成乙基 9-芳基-7-甲基-2,4-二硫代-2,3,4,9-四氢-1H-噻唑并[3,2-a:4,5-d'] dipyrimidine-8-carboxylates,与苯甲酰溴反应生成乙基 8-methyl-10-(4-methoxyphenyl)-3-located-5-thioxo-2(un)subatituded-10H-thiazolo[3'',2' ':1',2']pyrimido[4',5':4
