Access to Phenolic Fungal Metabolites via the Acid-catalysed Claisen Rearrangement. The Total Synthesis of (+/-)-Mellein, Aurocitrin, and 5',6'-Dihydroaurocitrin

Regioselective trifluoroacetic acid catalysed rearrangement of allyl 5-allyloxy-2-hydroxybenzoate (2b) with concomitant cyclisation of the initial product permits the simple preparation of 3,4-dihydro-5,8-dihydroxy-3-methylisocoumarin (5).Hydrogenolysis of the non-hydrogen bonded hydroxy group yields (+/-)-mellein (7) whereas elaboration of the lactone moiety of compound (5) provides access to aurocitrin (8b) and its side chain analogues.
