A revised structure for (-)-dihydropertusaric acid, a γ-butyrolactone acid from the lichen Punctelia microsticta

The γ-butyrolactone acid (1) and two known compounds, (-)-isomuronic acid and the tridepside gyrophoric acid, have been isolated from the lichen Punctelia microsticta. The structure and stereochemistry of compound 1 were determined on the basis of spectroscopic evidence and molecular modeling. Spect...
