A tandem deprotection/coupling sequence is reported for solution-phase peptide synthesis in water under micellar catalysis conditions using the designer surfactant TPGS-750-M. Cbz deprotection followed by peptide coupling in the presence of COMU and 2,6-lutidine afforded polypeptides containing up to 10 amino acid residues. A broad scope characterizes this new technology. No epimerization has been detected. The associated E Factors, as a measure of "greenness" and known to be extremely high for peptide couplings, have been reduced to less than 10 due to the step-economy and minimal amounts of organic solvent needed for product extraction.

Z or Fmoc amino acid fluorides have been prepared from the protected amino acids and cyanuric fluoride, and have been tested both in the condensation with simple amino acid esters and in Solid Phase Peptide Synthesis.
