Synthesis of Fluorinated Cyclopropyl Amino Acid Analogues: Toward the Synthesis of Original Fluorinated Peptidomimetics.

A straightforward, easy, and practical access to various amino acid analogues (methionine, leucine, lysine, and arginine) from a unique fluorinated cyclopropane scaffold is described. Moreover, the synthesis, for the first time, of one tripeptide incorporating a fluorinated cyclopropane amino acid (FCAA) analogue is reported.
