Sp. Green et Da. Whiting, BIOMIMETIC SPIROCYCLISATION USING NOVEL INTRAMOLECULAR RADICAL OXYGENATION A MODEL FOR THE BIOSYNTHESIS OF THE INTERIORIN LIGNANS, Journal of the Chemical Society, Chemical Communications, (21), 1994, pp. 2441-2442
Novel intramolecular radical spirocyclisation reactions in aromatic nu
clei, 22 --> 23 and 30 --> 31, are presented, which mimic a key step i
n the proposed biosynthesis of the interiorins 1-4 and kadsulignans 5,
