Abstract

4,5-Dibenzoyl-1H-pyrrole-2,3-diones and 4-benzoyl-5-phenyl-1H-pyrrole-2,3-diones reacted with 3-arylamino-1H-inden-1-ones at a molar ratio of 1:2 to give substituted spiro[diindeno[1,2-b:2′,1′-e]pyridine-11,3′-pyrroles]. The molecular and crystal structures of 4′,5′-dibenzoyl-1′-(4-methoxyphenyl)-5-phenyl-5H-spiro[diindeno[1,2-b:2′,1′-e]pyridine-11,3′-pyrrole]-2′,10,12(1′H)-trione were determined by X-ray analysis.
