Synthesis of 5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one derivatives

The reaction of 2-aminothiazoles with ethyl acetoacetate in acetic or polyphosphoric acid gave a series of 5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one derivatives which were nitrated with a mixture of nitric and sulfuric acid to 6-nitro-5H-[1,3]thiazolo[3,2-a]

Synthesis and biological evaluation of substituted thiazolamine, imidazo [2,1-b] thiazol-6(5H)-one, thiazolo [3,2-a] pyrimidin-5-one and thiazolyl thiourea derivatives

Substituted phenyl thiazole-2-amines (TA1-4) refluxed with ethyl acetoacetate using phosphorus oxychloride and polyphosphoric acid as a catalyst yielded thiazolo- pyrimidines (TP1-4) and with chloroacetic acid in ethanol furnished imizado- Thiazolos (IT1-4). Thiazolyl thioreas (TT1-4) were synthesized by the reaction of TA1-4 with ammonium thiocynate in dil hydrochloric acid. The structures of the synthesized compounds have been established on the basis of their spectral data and drug likelines was analyzed using Molinspiration online resource. The in vitro tuberculostatic potential evaluated against H37Rv strain of Mycobacterium tuberculosis by REMA assay has shown moderate activity for compound IT2. Synthesized compounds were screened against Staphylococcus aureus (MTCC 3160), Bacillus subtilis (MTCC 441), Escherichia coli (MTCC 40) and Pseudomonus aeruginosa (MTCC 424) bacteria and have shown significant activity.
