Methyl 1-aryl-3-cinnamoyl-4,5-dioxo-4,5-dihydro-1H-pyrrole-2-carboxylates interact with 3-(arylamino)-1H-inden-1-ones to give the corresponding 1,1'-diaryl-3'-cinnamoyl-4'-hydroxy-1H-spiro[indeno[1,2-b]pyrrole-3,2'-pyrrole]-2,4,5'(1'H)-triones in good yields.
Keywords: pyrrole-2,3-diones; enamines; spiro[indeno[1,2-b]pyrrole-3,2'-pyrroles] pyrrole-2,3-diones; enamines; spiro[indeno[1,2-b]pyrrole-3,2'-pyrroles]
