Abstract

Methyl 3-aroyl-2-chloro-1-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)-4,5-dioxo-4,5-dihydro-1H-pyrrole-2-carboxylates reacted with N,N′-diphenylguanidine to give 9-aroyl-8-hydroxy-2-imino-6-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)-1,3-diphenyl-1,3,6-triazaspiro[4.4]non-8-ene-4,7-diones whose structure was confirmed by 1H NMR and IR-spectroscopy.
