Structural characterization of 3,4-disubstituted γ-peptide and 2,3-disubstituted β-peptide foldamers derived from common multifaceted β-nitromethyl γ-amino acids and the chemical transformation of the β-nitromethyl group in γ-peptides into various functional derivatives are reported. The γ3,4-oligomers and α,γ-hybrid peptides showed characteristic C14-and C12-helical conformations in single crystals
