We report herein the synthesis of a fully functionalized B,C,D-ring system of lancifodilactone F. The key transformations involve an arene-olefin meta-photocycloaddition reaction and a palladium-catalyzed oxidative C-C cleavage reaction to establish its B,C-rings.
Keywords: cycloaddition; oxidation; palladium; photochemistry; terpenoid.
