New methodology for carbon-carbon bond formation, suitable for the construction of quaternary carbon centers, is described.The procedure involves the intramolecular reaction of an alkene with a cyclohexadiene-Fe(CO)3 complex at elevated temperature (140 d
Control of Absolute Stereochemistry during Ene-type Coupling between Diene-Fe(CO)3 Groups and Alkenes

Excellent stereocontrol during the ene-type coupling between diene-Fe(CO)3 groups 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.
