Tert-Butyl N-[(11-exo-benzyl-oxy-carbonyl-8-oxopenta-cyclo-[5.4.0.0.0.0]undecane-11-endo-yloxy)carbon-yl-methyl]carbamate.

ABSTRACT: 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 within the cage structure.

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 within the cage structure. ...[more]
