Design, Synthesis, and Application of a Trifluoromethylated Phenylalanine Analogue as a Label to Study Peptides by Solid-State <sup>19</sup>F NMR Spectroscopy.
The article discusses research on trifluoromethylated phenylalanine analogue design, synthesis, and application as labels for solid-state fluorine-19 nuclear magnetic resonance (F NMR) spectroscopy. It cites use of trifluoromethyl-substituted compounds as replacement for alipathic amino acids necessary in F NMR spectroscopy. It describes inter- and intramolecular interactions between phenylalanine and other aromatic residues. Brief details about the design of a novel F NMR label are offered.
