The total synthesis of the title compound 1b is described.Starting from simple orcinol and β-orcinol units, the benzophenone 4 has been prepared.Using a biomimetic reaction, the intramolecular oxydative coupling, lead to the grisadienedione 25.By thermal interconversion and permethylation, the depsidone 1b has been obtained.
