Cyclic imines bearing CF 3 and C 2 F 5 group were successfully used for the first Ugi multicomponent synthesis of polyfluoroalkyl-substituted proline, homoproline, and azepan carboxylic acid derivatives. Based on the suggested reaction the first synthesis of dipeptides containing α-CF 3 cyclic amino acids residue was described. The scope and limitations of the approach are discussed.
