3-Aroyl-1H-pyrrolo[2,1-c][1,4]benzoxazine-1,2,4-triones react with N'-(5,5-dimethyl-3-oxocyclohex-1-en-1-yl)benzohydrazides to give the corresponding N-[3'-aroyl-4'-hydroxy-1'-(2-hydroxyphenyl)-6,6-dimethyl-2,4,5'-trioxo-1',4,5,5',6,7-hexahydrospiro[indole-3,2'-pyrrol]-1(2H)-yl]benzamides. The molecular and crystalline structure of one of the products, N-[3'-benzoyl-4'-hydroxy-1'-(2-hydroxyphenyl)-6,6-dimethyl-2,4,5'-trioxo-1',4,5,5',6,7-hexahydrospiro[indole-3,2'-pyrrol]-1(2H)-yl]-3-nitrobenzamide, was determined by X-ray analysis.
