    The heterocyclic ring in the title compound, C27H34N2O6, has an envelope conformation on one of the bridgehead C atoms. Two strong intramolecular O-H...N hydrogen bonds stabilize the molecular conformation. The benzoate groups differ in therelative orientations of the ethyl groups, as quantified by the values of the C-O-C-C torsion angles of -86.5 (2) and -178.97 (17)°. The carbonyl groups are nearly coplanar with the benzene rings, forming C-C-C-O torsion angles of 0.9 (3) and 3.4 (3)°. The crystal structure is stabilized by weak intermolecular C-H...O interactions.
