The synthesis of Boc-or Fmoc-monoprotected propylenediamine derivatives is reported starting from N-protected a-amino acids. The introduction of these building blocks on solid support via the formation of a urea moiety leads to a new pseudopeptide family (Ca-CHe-CH~-Na(R)-CO-NH-Ca). Two carbonylati
