Terminal γ,δ-unsaturated amino acids, easily available by Claisen rearrangement or palladium-catalysed allylic alkylation, are excellent substrates for radical thiol additions. These clickreactions allow the introduction of highly functionalized side-chains into a given amino acid or peptide. This protocol is suitable for the modification of all kinds of terminal alkenes, such as allyl protecting

Deprotonation of peptides in the presence of zinc chloride gives rise to highly reactive nucleophiles that can be subjected to palladium-catalyzed allylicalkylation reactions. Excellent diastereoselectivities are obtained that are nearly independent of the allylic substrate used. By using this protocol, highly functionalized side chains can also be incorporated in excellent yields and selectivities
