corresponding sulfonic acid derivatives occurred. Further, acylation of the 7-NH2 group of 5H-thiazolo[3,2-a]pyrimidin-5-ones afforded amide derivatives, and reduction of the NO2 group of 5H-thiazolo[3,2-a]pyrimidin-5-ones gave amino derivatives. All the new compounds were confirmed by 1H NMR, 13C NMR, IR and HRMS spectra, and their antibacterial and antitubercular activities were screened. Some compounds showed
通过噻吩环闭合合成了新颖的5 H-噻唑并[3,2-a]嘧啶-5-酮。第一步是通过6-取代的2-硫尿嘧啶与适当的取代的苯甲酰卤的反应合成S-烷基化的衍生物。处理后的小号在不同温度下,分子内环化以3-(取代苯基)烷基化衍生物-5 ħ -噻唑并[3,2-a]嘧啶-5-酮或环化产物的磺化的相应的磺酸衍生物发生。此外,将5 H-噻唑并[3,2-a]嘧啶-5-酮的7-NH 2基团酰化得到酰胺衍生物,并还原5 H的NO 2基团。-噻唑并[3,2-a]嘧啶-5-酮产生氨基衍生物。所有新化合物均通过1 H NMR,13 C NMR,IR和HRMS谱图确认,并筛选了它们的抗菌和抗结核活性。一些化合物显示出显着的抗菌和抗结核活性。
