چکیده
The structure of the title compound, C(25)H(27)NO, is a mono-ketone penta-cyclo-undecane (PCU) mol-ecule bearing a tertiary amine group. One of the methyl-ene groups in the PCU is disordered over two orientations with site-occupancy factors of 0.621 (7) and 0.379 (7).

The structure of the title compound, C(26)H(29)NO(7), at 173 K has an inter-molecular N-H⋯O hydrogen bond. This is one of the few examples where a mono-ketone penta-cyclo-undecane (PCU) mol-ecule exibits hydrogen bonding in the solid state. The dihedral angles of the amide and ester groups are normal and unaffected by the cage structure. A longer than normal C-C bond [1.571 (4) Å] was found wit...

The title compound, C(33)H(36)N(2)O(8), is the first example of a disubstituted peptidic pentacycloundecane (PCU) diol. The structure displays an array of inter- and intra-molecular hydrogen bonding by both amide and alcohol functional groups. This hydrogen-bonding system connects the mol-ecules into a three-dimensional network.

The title compound 1-OPBB, C(19)H(19)BrO(2), contains a dechlorinated and hydrogenated isodrin backbone with an anti-4-bromo-benzoate substituent at one of the methano bridges. The dihedral angle between the CO(2) ester plane and the benzene ring plane is 8.5 (2)°. In the crystal, the ester groups stack over benzene rings: the mol-ecules pack as conformational enanti-omers, with nearest paralle...
