Phomenone, a known phytotoxic and mycotoxic sesquiterpene, afforded a new substituted benzofuran, by treatment with a H2SO4 in MeOH solution (10%). The structure of such compound, determined by spectroscopic and X-ray diffraction methods on its acetylderivative, is described. The formation mechanism of the new substituted benzofuran from the toxin is also discussed.
