                                3-Aroyl-1H-pyrrolo[2,1-c][1,4]benzoxazine-1,2,4-triones reacted with 5,5-dimethylcyclohexane-1,3-dione to give 3'-aroyl-4'-hydroxy-1'-(2-hydroxyphenyl)-6,6-dimethyl-6,7-dihydrospiro[1-benzofuran-3,2'-pyrrole]-2,4,5'(1'H,5H)-triones. The crystalline and molecular structures of 3'-benzoyl-4'-hydroxy-1'-(2-hydroxyphenyl)-6,6-dimethyl-6,7-dihydrospiro[1-benzofuran-3,2'-pyrrole]-2,4,5'(1'H,5H)-trione were determined by X-ray analysis.
