A series of nylon-like oligomers was synthesized, which consisted of alternating cyclic 1,2-diamine and 1,2-dicarboxylic acid building blocks with a five-membered ring constraint. The nylon 2 4 oligomers are symmetric and display helical structures similar to the β-peptide 12-helix with intramolecular 12-membered ring hydrogen bonds. The cyclopentane moiety allows each building block to promote 12-helical folding. In addition, a tartaric acid derivative with the acetonide moiety increases the solubility of oligomers in common organic solvents and promotes helical folding.
