The synthesis of β-ionone analog tricarbonyliron complexes was investigated. N-Methoxy-N-methyl-(2, 6, 6-trimethyl-1-cyclohexen-1-yl)-2-propenamide (Weinreb amide), prepared from the corresponding ethyl ester and N, O-dimethylhydroxylamine hydrochloride, reacted smoothly with various organometallic reagents to afford the β-ionone analogs in good to excellent yields. Treatment of these compounds with dodecacarbonyltriiron afforded the corresponding tricarbonyliron complexes in high yields.
