Abstract

Synthesis of Furo[2,3-d]pyridazin-4(5H)-one and Its N(5)-SubstitutedDerivatives. -A new and efficient method for the synthesis of furopyridazinone derivatives via intramolecular cyclization reactions of 2-hydrazonomethylfuran-3-carboxylate derivatives is developed. -(KARAHAN, E.; KOZA, G.; BALCI*, M.; Helv.
