Metallo-foldamers with backbone-coordinative oxime peptides: control of secondary structures.

Metal-mediated secondary structures of peptide-based foldamers were constructed using artificial backbone-coordinative oxime peptides. Complexation of the peptides with Pd(II) afforded several mononuclear and dinuclear secondary structures such as helices and hairpins as confirmed by single-crystal XRD and NMR analyses.
