    • For example, the synthesis of a 20 residue peptide in which residue 11 is varied to incorporate each 4-substituted proline derivative described herein would require 7 x 11 = 77 amide coupling cycles (with each cycle including deprotection, coupling, and wash steps) after the resin split via standard methodology, versus 11 amide coupling cycles using proline editing, a significant reduction in required time and material resources. In addition, only seven manual on-resin reactions, in total, are required to prepare all seven derivatives (Scheme 2), versus 27 solution-phase synthetic steps to prepare the required Fmoc amino acids from trans-hydroxyproline methyl ester.

    • Acetylation of the hydroxyl group was alternatively used as an effective orthogonal hydroxyl side chain protection strategy. See Supporting Information for details.
