Using two different conditions for the BAIB [bis(acetoxyiodo)benzene] oxidation to tetrahydro-beta-naphthols or substituted tetrahydro-beta-naphthols furnished two different products with excellent yields.

in 6–7 steps from the common precursor 18b. The key naphthalenones 6 were prepared in 5 steps from tetralone 17 in a regioselective manner. Anionic annulation of cyanophthalide 7c with 6 readily provided tetracyclic precursors 5 in excellent yields, sunlight-promoted photooxidation of which led to the synthesis of the title compounds.
