The synthesis of enantiopure N-benzylidene nitrones of N-hydroxy-α-amino acids and their incorporation using standard Fmoc-based peptide chemistry into solid-supported peptide chains is described. Deprotection and resin cleavage affords N-terminal peptide hydroxylamines, which are the key substrates for chemoselective ligations with C-terminal peptide α-ketoacids. This general route is applicable to

homogeneous oligopeptides based on the repeating decapeptide unit of the protein. The fully protected decapeptide 10 has been synthesized from appropriately protected amino acid building blocks using a fragment condensation strategy. A key feature of the strategy is the late incorporation of the synthetically valuable dihydroxyproline residue. This synthesis of the orthogonally protected repeating decapeptide
