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
常见的多面β-硝基甲基γ-氨基酸衍生的3,4-二取代的γ-肽和2,3-二取代的β-肽折叠剂的结构表征以及γ-肽中的β-硝基甲基化学转化为各种功能衍生物被报道。的γ 3,4 -oligomers和α,γ-混合肽显示特性C 14 -和C ^ 12在单晶螺旋构象。此外,尽管H键的几何形状较差,新的2,3-二取代的无环β-肽仍显示出C 6-螺旋构象。
