Conformationally diverse peptides containing 4-substituted proline residues a-g were synthesized from inexpensive Fmoc-trans-hydroxyproline via post-synthetic modification. Peptide A containing a trans-hydroxyproline residue was easily transformed into peptides a-g through several reaction sequences using DAST, PDC, and/or Mitsunobu conditions on the solid-support followed by the standard cleavage from the resin. Conformational properties of these peptides were also studied by NMR.
