Abstract
Ethyl 4,5-dioxo-2-phenyl-4,5-dihydro-1H-pyrrole-3-carboxylates reacted with malononitrile (methyl cyanoacetate) and 4-hydroxycoumarin to produce substituted ethyl 2-amino-2′,5-dioxo-5′-phenyl-1′,2′-dihydro-5H-spiro[pyrano[3,2-c]chromene-4,3′-pyrrole]-4′-carboxylates. The crystal and molecular structure of ethyl 2-amino-3-cyano-1′-cyclohexyl-2′,5-dioxo-5′-phenyl-1′,2′-dihydro-5H-spiro[pyrano[3,2-c]chromene-4,3′-pyrrole]-4′-carboxylate was determined by X-ray analysis.
