Abstract
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.
