Nucleation of the β-hairpin structure in a linear hybrid peptide containing α-, β- and γ-amino acids

Synthesis and conformational studies of a short linear peptide containing a pyrrole amino acid (1, Paa) and a furan amino acid (2, Faa), namely Boc-hGly-Faa-d-Pro-Gly-Paa-hGly-Faa-OMe (3), were carried out in which it was established that peptide 3 adopted a well-defined β-hairpin structure in DMSO-d6.
