- Abstract
Methyl 4-aryl-2-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-ylamino)-4-oxobut-2-enoates reacted with oxalyl chloride to give methyl 3-aroyl-2-chloro-1-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)-4-hydroxy-5-oxo-2,5-dihydro-1H-pyrrole-2-carboxylates which were hydrolyzed to methyl 3-aroyl-1-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)-2,4-dihydroxy-5-oxo-2,5-dihy-dro-1H-pyrrole-2-carboxylates. The structure of the later was confirmed by X-ray analysis.
