Synthesis of Some Novel Thiazolo[3,2‐a]pyrimidine and Pyrimido[2,1‐b][1,3]thiazine Derivatives and their Antimicrobial Evaluation |
| |
Abstract: | A 2‐(2‐Mercapto‐4‐(4‐phenoxyphenyl)‐6‐(thiophen‐2‐yl)‐1,6‐dihydropyrimidin‐5‐yl) acetic acid was used as a reactive key precursor to design various pyrimidine derivatives such as thiazolo3,2‐a]pyrimidines and pyrimido2,1‐b]1,3]thiazines. The chemical structures of the newly synthesized products were confirmed by their elemental analyses and spectral data (IR, 1H NMR, 13C NMR, and mass spectra). The antibacterial and antifungal activities of some of the synthesized products were also evaluated, and it was found that compounds 3, 5, 9 , and 11 exhibited potent activity against tested microorganisms in comparison with standard drugs. |
