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.

Research communications

Research communications are designed to help authors bring out the science behind their structure determinations. Authors are encouraged to report more than one structure in the same communication and also to include the results of investigations with other techniques. The Research communications format makes Acta E the natural home for structure determinations with interesting science to report.

Emerging Sources Citation Index

Acta E is included in the Emerging Sources Citation Index.
