Oxidative coupling of furans and naphthoquinones: a potential route to anthracyclinones

Abstract
2-Furyl-1,4-naphthoquinones have been prepared by treatment of mixtures of furans and naphthoquinones with chloranil and other oxidants, and used to synthesize quinizarin and 6,11-dihydroxynaphthacene-5,12-dione in a reaction sequence which promises great versatility.
