2-(1-Hydroxy-4,4-dimethyl-2-oxobutyl)-4-methoxy-1-naphtholactone

The crystal structure of the tricyclic keto lactone, C₁₈H₁₈O₄, has been determined by X-ray diffraction. The eight-membered heterocyclic ring in the molecule displays a distorted boat conformation in contrast to the more favoured boat-chair conformation in various oxygen-containing eight-membered ring systems.
