Article abstract of DOI:10.1016/0040-4039(81)80150-5

Optically active tricarbonyl(cyclohexadienyl)iron(1+) salts I, II and III are examples of olefin complexes with molecular asymmetry due to coordination with a transition metal.Their reactions serve to direct the eventual specific formation of a new chiral centre of known absolute configuration.The absolute configuration of the 2-methoxy-5-methyl salt I is defined and its application to the asymmetric synthesis of γ-disubstituted cyclohexanones is described.
