Treatment of benzyl 4-oxo-1-(phenylsulfonyl)cyclopent-2-ene-1-carboxylate (11) with amine base provides in situ generation of the cyclopentadienone moiety which has been shown to react with various dienes. Reaction temperature decreases up to 100°C were noted for these activated substrates by comparison to the corresponding "nonactivated" 3-carboalkoxycyclopentenone cycloadditions.
