Abstract
b3-Heptadepsipeptides with the hydroxybutanoic acid unit at various positions in the peptidic sequence were synthesized in soln. using Boc-protection and/or Z-protection. DCC/DMAP or EDC/DMAP coupling conditions were used for the ester bond formation and EDC/HOBt for the amide bonds. Structural investigations by CD and NMR spectroscopy point to the importance of the contribution of hydrogen bonds on the stability of the 314-helix over that of the b-amino acid residue's backbone.
