In (1S,2R,3S,4R)-3-benzamido-3-methoxycarbonylbicyclo[2.2.1] heptane-2-carboxylic acid, C17H19NO5, the values determined for the torsion angles about the N-Cα(φ) and Cα-CO(ψ) bonds correspond to a semi-extended conformation for the amino-acid residue. The crystal structure is stabilized by two intermolecular hydrogen bonds (O-HO and N-HO) involving the benzamido, carboxylic acid and methyl ester groups.
