摘要

The conformational properties of β-peptides comprised of enantiomerically pure trans-2- aminocyclohexanecarboxylic acid (ACHC) or trans-2-aminocyclopentanecarboxylic acid (ACPC) units were studied by NMR spectroscopy in organic solvents. In pyridine-d 5 solution, ACPC hexamer 1 and ACPC octamer 2 displayed well-defined helical structures characterized by a series of 12-membered hydrogen-bonded rings (“12-helix”). The ...
