Key words

peptide bond formation - nitrophenyl esters - amino acids

Significance

Reactive amino acid phenyl esters have been used in peptide synthesis. In 2002, Keillor­ and co-workers reported a method for peptide bond formation between p-nitrophenyl esters and unprotected amino acids in aqueous solution.

Comment

By using p-nitrophenyl esters formed in situ, various dipeptides or tripeptides were synthesized without classical peptide-coupling reagents. The yields of the target peptides were moderate to excellent.
