Reference Reading

1. A revised structure for (-)-dihydropertusaric acid, a gamma-butyrolactone acid from the lichen punctelia microsticta
MS Maier, Gonzalez Marimon DI, CA Stortz, MT Adler J Nat Prod. 1999 Nov;62(11):1565-7. doi: 10.1021/np990110n.
The gamma-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. Spectroscopic and physical data of 1 and (-)-dihydropertusaric acid, previously isolated from the lichen Pertusaria albescens, showed that both are the same compound, although for the latter the epimeric structure 2 has been proposed.
