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 N‐terminal position was achieved. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
