Synthesis of Echinotinctone, A Fungal Fluorone Pigment

Echinotinctone (3) is formed by acid-catalyzed condensation of 1,2,4-trihydroxytoluene (1) with orcylaldehyde (2), a reaction mimicking the probable biosynthesis. A more efficient stepwise synthesis proceeds via the benzophenone intermediate 11, which can be converted to 2,6-dihydroxy-1,8-dimethyl-3H-xanthenn-3-one (3) by LiAlH4 reduction and subsequent acid-catalyzed ring closure.
