(1,1-Dihydroperfluoroalkyl)phenyliodonium N,N-bis(trifluoromethylsulfonyl)imides (4, n = 0-2) were synthesized and used to transfer the corresponding 1,1-dihydroperfluoroalkyl groups to the a-amino group Of (L)tyrosine. The obtained N-alpha-2,2,2-trifluoroethylated (L)tyrosine (6, n = 0) was further used as the N-terminus in the solid phase peptide synthesis of leucine enkephalin analogue. The lipophilicity of the N-alpha-1,1-dihydroperfluoroalkylated (L)tyrosines (6, n = 0-2) and N-terminus-2,2,2-trifluoroethylated leucine enkephalin analogue (7), as well as the corresponding parent compounds, was measured.
