N2 - The title dilactone has been resolved into its enantiomers (+)-(S,S)-1 and (-)-(R,R)-1, whose absolute configurations were found by X-ray diffraction analysis of intermediate lactonic amide 2a; the magnitude of the n-π* Cotton effect increased with an increase in folding or a diminution in twist of the boat conformation of a dilactone ring.
