INTRAMOLECULAR RADICAL COUPLING OF A PHENOLIC ENOLATE: OXIDATIVE FRAGMENTATION OF THE SPIRODIKETONE INTERMEDIATE
Ferricyanide oxidation of the dianion of the phenolic β-diketone 6b in basic conditions effects intramolecular radical coupling to form the spirocyclic diketone 7 which leads to the hydroxy tetralone 8 via an oxidative fragmentation process.
