A previously described mixture of bicyclo[4.4.0]decanecarbonitriles [(4) and (5)] was converted, via a nine-step sequence of reactions, into (±)-isolinaridiol (3), which was readily transformed into the corresponding diacetate (2).

[reaction: see text] A stereoselective synthesis of (-)-ilimaquinone (4) is presented. The synthetic strategy is based on a novel radical decarboxylation and quinone addition methodology that produces quinone 7 from reaction of thiohydroxamic acid derivative 8 with benzoquinone (9). Final functionalization of 7 to ilimaquinone (4) is achieved by exploring the electronic effects of the residual thiopyridyl
