Two different strategies have been employed for the synthesis of Fmoc-protected β3-homoarginine; the Arndt-Eistert homologation of α-arginine and the guanidinylation of β3-homoornithine. Solid-phase β-peptide synthesis was used for the preparation of β-heptapeptide 1, which was designed to form a helix stabilized by electrostatic interactions through positively (β3hArg) and negatively charged (β3hGlu) amino acid residues. CD measurements and corresponding NMR investigations in MeOH and aqueous solutions do indeed show that the β-peptidic 314-helix can be stabilized by salt-bridge formation.
