Synthesis and antimicrobial activity of new functionalized derivatives of [1,2,4]triazolo[4,3-a]pyrimidin-5(1H)-one

New functionalized 1,7-diaryl-6-cyano-1,2,4-triazolo[4,3-a]pyrimidin-5(1H)- one derivatives (5a-j) were synthesized via reaction of 5-cyano-6-phenyl-2- thiouracil 1 with the respective hydrazonoyl halides 2a-j and their biological activity was evaluated.

Reactions with hydrazonoyl halides 45: Synthesis of some new triazolino [4,3-a]pyrimidines, pyrazolo [3,4-d]pyridazines, isoxazolo[3,4-d]pyridazines, and thieno[2,3-b]pyridines

Triazolino[4,3-α]pyrimidines pyrazolo[3,4-d]pyridazines and isoxazolo[3,4-d] pyridazines were synthesized from hydrazonoyl halides. Also, 3-aminothieno[2,3-b] pyridines and pyrimidino[4′,5′:4,5]thieno[2,3- b]pyridines were synthesized from cynothioacetamide. Structures of the newly synthesized compounds were established on the basis of elemental analyses and spectral data. Copyright Taylor & Francis LLC.
