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-a]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 compound...

Description
Summary:Triazolino[4,3-a]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.
