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.

Dihydroxyserrulatic acid (1), a diterpene from Eremophila serrulata, has been degraded to the naphthalene (2) which was shown to have the R-configuration. The diterpene acid can now be designated as (5R,8S,1'S)-4-hydroxy-8-(6'-hydroxy-1',5'-dimethylhex-4-enyl)-5-methyl-5,6,7,8-tetrahydronaphthalene-2-carboxylic acid.

Abstract The reaction of β-himachalene with dichlorocarbene followed by ruthenium catalyzed oxidation under Sharpless conditions yields 8,8-dichloro-3,3,7-trimethyl-1(3-oxobutyl)bicyclo[5.1.0]octane-2- carboxylic acid (3). The absolute configuration was determined crystallographically to be (1S, 2R, 7R).
