  Synthetic tactics of new class of 4-aminothieno[2,3-d]pyrimidine-6-carbonitrile derivatives acting as antimicrobial agents

  摘要：

  Thermal selective reactions were studied on oxothieno[2,3-d]pyrimidine-6-carboxamide 3 with POCI3 and PCI5. At 25-50 degrees C, the C-7-amide rearranges to nitrile furnished compound 4 in 85-90% yield, while at 80-110 degrees C furnished mixture of products 4 and 5 in 28-68% yields. The chloro displacement with amines in compound 5 yielded 4-aminothieno[2,3-d]pyrimidine-6-carbonitrile derivatives 8(a h) and 9(a e). Antimicrobial activity of new compounds was studied against several bacteria such as Staphylococcus aureus MTCC-96, Escherichia coli MTCC-443, Pseudomonas aeruginosa MTCC-4 41, Streptococcus pyogenes MTCC-442 and fungi Aspergillus niger MTCC-282, Aspergillus clavatus MTCC-1323, Candida albicans MTCC-227 using broth microdilution method. Compounds 4, 8b, 8d, 8e, 8h and 9a showed promising antibacterial activity compared to ampicillin and compounds 8b, 8h showed better antifungal activity compared to greseofulvin.

  o‐Aminothiophene dicarbonitrile 1 on neat reaction with cyclic ketones in anhydrous ZnCl2 yielded mixture of fused aminopyridine 3 and iminospirooxazine 4 derivatives. Similarly, pyrimidine derivatives 5 and 8 were obtained by the reaction of this intermediate 1 with formic acid and DMF‐DMA followed by hydrazine hydrate, respectively. The reaction of o‐amino‐thiophene dicarboxamide 2 at ambient temperature
