ChemInform Abstract
The title tripeptides (I) are prepared by incorporating the corresponding ketone amino acid derivatives (II) or (III) by coupling with carbonyl bis(3-methylimidazolium triflate). During peptide bond formation, the keto group of the glutamyl residue requires protection, which is provided as the ethylene dithioketal in the form of (III).
