Abstract :
A number of new 4-substituted-3-alkoxy-2-butenoic acid esters have been synthesized through the reaction of ethyl (2E)-4-bromo-3-alkoxybut-2-enoates with phenols or naphthols in the presence of potassium carbonate and acetone. Treatment of these esters with hydrazine hydrate in ethanol afforded new pyrazol-3-one derivatives. The newly synthesized compounds were characterized by elemental analysis, NMR spectroscopy and mass spectrometry.
