Cover illustration: 9,10-Dihydroanthracene-succinimides are target molecules for pharmaceutical and medical uses and their related pyrrolidines have also found applications as organocatalysts. In the title compound, C25H23N·CHCl3, the N atom of the pyrrolidine heterocycle exhibits a pronounced pyramidalization [[Sigma](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. In view of the presence of the chloroform solvent molecule is was possible to confirm crystallographically that the absolute configuration at the C-atom fused positions of the pyrrolidine group are S and R.
