Abstract
A carboxylic acid-catalysed transamidation of Boc-protected diketopiperazines (Boc-DKPs) was developed in this study, which allowed access to various tripeptides featuring a D-proline residue in good-to-high yields within 30 min. Subsequent coupling reactions between the Boc-DKPs and di-, tri-, and tetrapeptide esters were successfully performed, furnishing the corresponding tetra-, penta-, and hexapeptides.
