A synthesis of the abietane diterpenoid quinone (±)-royleanone via maleoylcobalt technology

Article abstract of DOI:10.1016/S0040-4039(00)97454-9

(±)-Royleanone has been synthesized by rapid construction of a highly substituted quinone using maleoylcobalt complex technology followed by acid induced cyclization of the corresponding hydroquinone methyl ether onto a tethered enone. The synthesis was completed by straightforward functional group manipulations.
