ChemInform Abstract: Synthesis of Some New Pyridazin‐3‐one Derivatives and Their Utility in Heterocyclic Synthesis.

Abstract

Synthesis. -New pyridazinone derivatives (IV) are synthesized by nucleophilic addition of benzylamine to butenoic acid derivatives (I) followed by cyclocondensation of the adducts with hydrazine hydrate. The behavior of the latter compounds towards different nucleophilic and electrophilic reagents is studied. -(EL-MOBAYED, M. M.; HUSSEIN*, A. M.; MOHLHEL, W. M.; J. Heterocycl.
