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.
