Brominated and iodinated allylic substrates can be subjected to palladium‐catalyzedallylic alkylation of amino acid and peptide ester enolates. The incorporation of a vinylic halide functionality into the allylic substrate allows a direct modification of the allylated peptide via cross coupling chemistry.

Ferrocenylallyl carbonates have been found to be suitable substrates for palladium-catalyzed allylic alkylation reactions. Amino acidester and peptide enolates were employed as nucleophiles for the regio- and stereoselective introduction of the redox-active ferrocenyl unit into peptide chains.
