title: 5-Benzyl-7-methyl-hexa-hydro-3a,7-methano-1H-furo[3,4-c]azocine-3,10(4H)-dione.
abstract: The title compound, C(18)H(21)NO(3), was obtained via a double Mannich condensation reaction of 6-methyl-tetra-hydro-isobenzofuran-1,7(3H,7aH)-dione with formaldehyde and benzyl-amine. The mol-ecule contains three fused rings of which the cyclo-hexa-none and piperidine rings adopt chair conformations and the furan-one ring assumes an envelope conformation. An inter-molecular C-H⋯π inter-action is present in the crystal structure.
