By following this route the conjugated parent alkaloid and derivatives with nitro, amino, as well as some alkanoylamino groups at C-7 were attached at the ferrocene moiety, thereby significantly extending the π system. In addition, the parent compound was subjected to the reaction by treatment with ferrocene-1,1′-dicarbaldehyde, giving ri to the double condensation product, which is only the cond ca of a 1,1′-disubstituted ferrocene derivative with two alkaloid substituents. A number of the compounds obtained were subjected to X-ray crystallographic analys. In all cas, the substituents adopt a coplanar conformation with
