Article abstract of DOI:10.1055/s-1996-4236

Aldolization reactions of 1-acetyl-1H-indol-3(2H)-one with glyoxal derivatives afforded (1-acetyl-3-oxo-2,3-dihydro-1H-indol-2-ylidene)acetic acid ester derivatives 2 and 3. Spiro compounds 6 were obtained by Diels-Alder reactions of 2; inverse electron demand Diels-Alder reactions of 2 afforded pyrano indoles 8.
