Heating of allylic amide or allylic ester substituted diene–Fe(CO)3complexes such as (7) and (10)(140 °C) results in an intramolecular coupling of the pendant double bond with the diene moiety to give spirolactam and spirolactone derivatives; the stereochemical course of this reaction was established by an X-ray crystal structure determination of the lactone derivative (11).
