摘要:
Isopropyl 2-(1-aryl-4,5-dioxo-2-phenyl-4,5-dihydro-1H-pyrrol-3-yl)-2-oxoacetates reacted with N-substituted 3-amino-5,5-dimethylcyclohex-2-en-1-ones to give the corresponding 1'-substituted (Z)-6',6'-dimethyl-3-[phenyl(arylamino)methylidene]-6',7'-dihydro-3H-spiro[furan-2,3'-indole]-2',4,4',5(1'H,5'H)-tetraones. The structure of 1'-benzyl-6',6'-dimethyl-3-[(Z)-phenyl(phenylamino)methylidene]-6',7'-dihydro-3Hspiro[furan-2,3'-indole]-2',4,4',5(1'H,5'H)-tetraone was proved by X-ray analysis.
