6]-tetracyclic core framework that exhibit a broad spectrum of biological activities. A synthesis of the common core of epicoccolide A and epicocconigrone A has been achieved using an umpolung alkylation–lactonization to assemble an isochromanone from which the bridged 1,3-dioxane was readily assembled. A different strategy was required to access the core on the integrastatins; an initial aryllithium addition

Condensation of 2-lithio-1-methyl-4-quinolone with methyl 2-(chloroformyl)benzoate gives 5-methylbenz[b]acridine-6,11-12-trione 3; addition of the anion of methyl 2-(1,3-dithian-2-yl)benzoate to 1-methoxycarbonyl-4-quinolone gives 5,5a-dihydro-11-hydroxy-5-methoxycarbonyl-12-oxaspirobenz[b]acridine-6,2'(1',3'-dithiane)}7.

The use of methyl 2-(1,3-dithian-2-yl)benzoate as a member of a new group of bidentate synthons in an improved annelation method, yielding polycyclic systems with three differentiated carbonyl groups, is described.
