Date of Publication
The title compound, a horminone derivative with the systematic name 7-acetyl-12-methoxyabieta-8,12-diene-11,14-dione, C23H32O5, was isolated from Hyptis verticillata from St. Mary, Jamaica. In the molecule, there are three fused six-membered rings, namely a substituted quinone ring in a slight boat conformation fused to a central acetyl- and methyl-substituted cyclohexene ring in a half-chair conformation, which is trans-fused to a dimethyl-substituted cyclohexane ring in a chair conformation. A single weak intramolecular C-H...O hydrogen bond links molecules into extended chains in the b axis direction.....
