Abstract
In the title compound, C25H23N·CHCl3, the dihydroanthracene 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 [Σ(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 molecule 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.
