The heterocyclic ring in the title compound, C(27)H(34)N(2)O(6), has an envelope conformation on one of the bridgehead C atoms [Q(2) = 0.4487 (19) Å and ϕ = 291.3 (2)°]. Two strong intra-molecular O-H⋯N hydrogen bonds stabilize the mol-ecular conformation. The benzoate groups differ in the relative orientations of the ethyl groups, as quanti-fied 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 ...[more]
