A convenient procedure for the synthesis of highly lipophilic dipeptide building blocks from enantiopure α-trifluoromethyl α-amino acids is reported. Coupling reactions at the C termini of the trifluoromethyl α-amino acids were successfully performed with totally unprotected amino acids without formation of diketopiperazines. The synthesis of a tripeptide through a coupling reaction at the deactivated
