enhancing the efficiency of peptide cyclization, and for fine‐tuning the conformations of cyclicpeptides, are valuable from a drug development perspective. Herein stereoselectivefluorination is investigated as a new strategy for achieving these goals. Four vicinal difluorinated analogues of the natural cyclic heptapeptide unguisin A have been efficiently synthesized. The analogues are found to adopt dramatically
