procedure for peptide‐bond formation is reported. Instead of activation of the carboxylic acid functionality, the reaction involves an unprecedented use of activated α‐aminoesters. The method provides a straightforward entry to dipeptides and was effective when a sensitive cysteine residue was used, as no epimerization was detected in this case. The applicability of this method to iterative peptide synthesis

The synthesis of dipeptides through a sequential one‐pot procedure from commercially available protectedaminoacids is described. The transformation relies on the use of in situ generated transiently CDI‐protected α‐amino esters (CDI, e.g. N,N′‐carbonyldiimidazole). In addition of being a highly atom‐economical process, the couplings take place under very mild and neutral conditions without adding
results in a significant advance in convergent peptide synthesis is described. Despite the observation of epimerization with low bulk substrates in preliminary studies, a systematic examination and understanding of the reaction mechanism enabled the development of a modified epimerization-free reaction whereby peptidefragmentcouplingsusingpeptide α-ketoacids were successfully achieved.
