Abstract: Three dibenzofuran-based amino acid residues, namely 4-(2-aminoethyl)-6- dibenzofuranpropanoic acid (l), 4-(aminomethyl)-6-dibenzofuranethanoic acid (2), and 4- amino-6-dibenzofuranmethanoic acid (3), were prepared in order to compare their physical properties so as to further understand residue 1's ability to nucleate antiparallel@-sheet formation within small peptides in aqueous solution. FT-IR, variable temperature NMR, ...
