The absolute configuration has been established of the enantiopureanti-head-to-head cyclodimer of anthracene-2-carboxylic acid (AC) cocrystallized with L-propinol and dichloromethane [systematic name: (S)-2-(hydroxymethyl)pyrrolidin-1-ium (5R,6S,11R,12S)-8-carboxy-5,6,11,12-tetrahydro-5,12:6,11-bis([1,2]benzeno)dibenzo[a,e][8]annulene-2-carboxylate dichloromethane monosolvate], C5H12NO+·C30H19O4−·CH2Cl2. In the crystal structure, the AC dimer interacts with L-prolinol through a nine-membered hydrogen-bonded ring [R22(9)], while the dichloromethane molecule is incorporated to fill the void space. The absolute configuration determined in this study verifies a recent assignment made by comparing theoreticalversusexperimental circular dichroism spectra.

The Absolute

The absolute configuration of the title compound, C24H23NO2, has been confirmed as 3R,4R. The hydroxymethyl group and phenyl ring at the asymmetric C atoms exhibit α and β orientations, respectively, and the non-planar heterocyclic ring of the tetrahydroisoquinoline system adopts an envelope conformation. The crystal structure is stabilized through hydrogen bonds.
