Site specific introduction of the polar hydrophobic trifluoromethyl-λ6-tetrafluorosulfanyl (CF3SF4) group can effectively control the secondary structure of a heptapeptide, the minimum repeat unit of an α-helix. The structural influence of CF3SF4-containing amino acid on the heptapeptide was established using NMR methods.
