Abstract
An efficient asymmetric synthesis of 6-aminobicyclo[2.2.1]heptane-2-carboxylic acid as a novel γ-turn mimic has been achieved. Structural analysis of the γ-amino acid derivative was carried out using 1H NMR spectroscopy and intramolecular hydrogen bonding between side chain amides confirmed the turn structure, which had been predicted by Ab initio computational study.
