ABSTRACT: In the title compound, C20H17NO3 (alternative name: N-hy-droxy-9,10-dimethyl-9,10-ethano-anthracene-11,12-dicarboximide), the rigid ethano-anthracene-dicarboximide moiety has a roof-shaped geometry, the inter-planar angle between the two terminal phenyl rings being 124.9?(6)°. In the crystal, mol-ecules are linked via O-H?O hydrogen bonds, forming chains along [010]. C-H?O and C-H?? inter-actions link adjacent chains, leading to the formation of a three-dimensional structure.

Project description:In the title compound, C(25)H(23)N·CHCl(3), the dihydro-anthracene unit is bent with a dihedral angle between the benzene rings of 57.82?(8)°. The N atom of the pyrrolidine heterocycle, which has an envelope conformation with the N atom as the flap, exhibits a pronounced pyramidalization [?(C-N-C) = 328.07°], indicating an accentuated N-donor character. In the crystal, this behaviour is evident by the C-H?N hydrogen bond involving a solvent mol-ecule and the N atom. The absolute configuration at the C-atom fused positions of the pyrrolidine group were crystallographically confirmed to be S and R.

Project description:The title compound, C11H8O5, features a 'skipped' diene, an anti-bis-(epoxide) and a cyclic carbonate, all embedded in a densely functionalized [4.4.3]propellane scaffold. The crystal packing of this diepoxide is effected primarily by C-H?O hydrogen bonds, which link the mol-ecules into tapes along the b axis. Inter-tape connectivity is brought about by centrosymmetrically disposed pairs of C?O contacts [3.183?(4)?Å] between the C(?+)=O(?-) dipoles of neighbouring carbonate moieties.
