Excellent stereocontrol during the ene-typecouplingbetweendiene–Fe(CO)3groups and alkenes can be achieved by appropriate substitution at C(5) of the diene ring, allowing the preparation of spirolactams and spirolactones in enantiomerically pure form, thus showing the cyclization reaction to be a valuable tool in the asymmetric construction of quaternary and spiro carbon centres.

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).
