Abstract
Abstract2-Bromo (2′-benzofuryl)glyoxal-2-arylhydrazonesI reacted with nucleophiles displacing the bromide. Treatment ofI with active methylene compounds yield the pyrazole derivativesVIII–XI. CompoundsXII–XIV reacted with hydrazine to give pyrazolo[3,4-d]pyridazine derivativeXIV–XVI. The structures of the products were assigned and confirmed on the basis of their elemental analysis and spectral data.
