In this report, we explore the feasibility of using bicyclic chiral β-amino acids,(1R, 2R, 4S)- and (1S, 2S, 4R)-7-azabicyclo [2.2. 1] heptane-2-carboxylic acid (R-Ah2c and S-Ah2c, respectively), to prepare novel peptides with unique properties. Facile cis–trans isomerization of the non-planar amide bonds of these β-amino acids should result in great flexibility of the backbone structure of β-peptides containing them. Indeed, oligomers of ...
