The total synthesis of bikaverin (1b) is described, from everninic acid (5) and 3,5-dihydrobenzoic acid (6).Dieckmann condensation of methyl 2-acetyl-3,5-bis(benzyloxy)phenylacetate (14), synthesised from (6), followed by treatment with protected everninic acid chloride (9) gave 1,3-bisbenzyloxy-6,8-bis(2-benzyloxy-4-methoxy-6-methylbenzyloxy)naphthalene (16).Photoinduced Fries rearrangement of (16) afforded 1,3-bis(benzyloxy)-7-(2-benzyloxy-4-methoxy-6-methylbenzoyl)-6-(2-benzyloxy-4-methoxy-6-methylbenzoyloxy)-8-hydroxynaphthalene (23).Ring closure of (23) with tetramethylammonium hydroxide in pyridine gave the angular benzoxanthene, 1,3-bis(benzyloxy-6-hydroxy)-10-methoxy-8-methylbenzo
