strategy for the synthesis of the carbocyclic portion of zoanthenol is disclosed. The key step involves a 6-endo radical-mediated conjugate addition that constructs the quaternary stereocenter at C(12) and closes the B ring in a stereoselective manner. The synthesis of the C-ring fragment uses an enantioselective desymmetrization to simultaneously establish the absolute stereochemistry of two vicinal
