Abstract
In -methoxycarbonylbicycIo[2.2.1]heptane-2-carboxylic acid, C17H19NO5, the values determined for the torsion angles about the N-C-alpha(psi) and C-alpha-CO psi) bonds correspond to a semi-extended conformation of the amino acid residue. The crystal structure is stabilized by two intermolecular hydrogen bonds (O-H ... O and N-H ... O) involving the benzamido, carboxylic acid and methyl ester groups.
