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
