Fmoc-Phe(4-I)-OH is utilized to prepare peptides containing the versatile Phe(4-I) residue.  4-Iodophenylalanine has been used to prepare substrates for 125I incorporation to be used in radiolabeling studies (DR Harding, WS Hancock, JT Sparrow, Int. J. Pept. Protein Res., 1985, 26, 208-13).  Phe(4-I) residues have been used in x-ray chrystallographic structure determination (RK Spencer, H Li, JS Nowick, J. Am. Chem. Soc., 2014, Just Accepted) and as spectroscopic probes to study the orientation of peptide binding to receptor pockets (V De Filippis, et al., Protein Sci., 2007, 16, 1257-65).  4-Iodophenylalanine has also been utilized in the preparation of thiophenylalanine-containing peptides (CR Forbes, NJ Zondlo, Org. Lett., 2012, 14, 464-7).  Phe(4-I) residues can be converted to alkynyl-phenylalanines by the Sonogashira reaction (U. Hoffmans, N Metzler-Nolte, Bioconjugate Chem., 2006, 17, 204-13) or to a variety of biarylalanines through Suzuki coupling (S Chen, et al., Biochemistry, 2013, 52, 8580-9; C Mapelli, et al., J. Med. Chem., 2009, 52, 7788-99).
