Abstract
Arylhydrazones are prepared and reacted with pyrazolylmethylene malononitrile derivatives yielding 2,5-dihydropyridazines substituted at C-5 by pyrazole derivatives. Utilizing azaenamine containing a cyano group at the ortho position enabled the formation of the condensed pyridazino[1,6-a]quinazoline derivatives. A subsequent acetylation of the synthesized pyridazines led to the formation of pyrimido[4,5-c]pyridazine compounds which can be considered as 4-deazatoxoflavin derivatives. All the new compounds were full-characterized by the different spectral tools and the unambiguous structural elucidation of 2,5-dihydropyridazines was done using 2D-HMBC spectroscopy.
