Sp. Green et Da. Whiting, NEW CARBON RADICAL CHEMISTRY AS A MODEL FOR THE BIOGENESIS OF THE INTERIORIN KADSULIGNAN TYPE OF DIBENZOCYCLOOCTADIENE LIGNAN/, Journal of the Chemical Society. Perkin transactions. I, (2), 1998, pp. 193-201
Novel intramolecular radical spirocyclisation reactions in aromatic nu
clei, 48-->49, 40-->22 and 34-->32, are presented, which mimic a key s
tep in the proposed biosynthesis of the interiorins 2a-d, the kadsulig
nans 3a,b and relatives.
