Synthesis of the azaphilones using copper-mediated enantioselective oxidative dearomatization.
An approach to the asymmetric synthesis of the azaphilone natural products is reported involving copper-mediated enantioselective oxidative dearomatization of o-alkynylbenzaldehydes. The approach was successfully applied to the synthesis of (-)-S-15183a and several unnatural azaphilones.
