Abstract

Isopestacin (1), an isobenzofuranone natural product was isolated in 2002 by Strobel and co-workers from culture broths of the endophytic fungus Pestalotiopsis microspora. 1 Its structure was determined by analysis of proton and carbon NMR data, and confirmed by X-ray crystallography. It is the first member of the isobenzofuranone family of natural products that contains a substituted benzene ring at C-3 of the benzofuranone ring. Strikingly, the resorcinol ...
