Article abstract of DOI:10.1007/BF00516451

1-Aryl-3-(2,4-dimethyl-5-ethoxycarbonyl-3-pyrrolyl)-5-oxopyrazoles were obtained by condensation of ethyl β-(2,4-dimethyl-5-ethoxycarbonyl-3-pyrrolyl)-β-ketopropionate with arylhydrazines.Electron-donor substituents in the aromatic ring of the arylhydrazines accelerate the cyclization of the intermediate hydrazones, whereas electron-acceptor substituents hinder cyclization.
