Abstract : A concise synthetic pathway yielding to hydrophobic α,α-disubstituted disilylated amino acids based on a hydrosilylation reaction is described. As a first example of utilization in solid-phase peptide synthesis, TESDpg was introduced in replacement of Aib in an alamethicin sequence, leading to analogues with modified physicochemical properties and conserved helical structures. This study highlights the potential of these new amino acids as tools for peptide modulation.
