Abstract. Pentafluorophenyluronium salts and related cou- pling reagents for the solid-phase synthesis of peptides and glycopeptides have been developed and employed in the ... In the field of peptide synthesis pentafluorophenyl es- ters of amino acids have been reported to be very effi- cient [ 11 in amide bond formation. Methods based on in situ formation of these activated carboxylic compounds have not been described so far. We report here on the synthesis ...
