Abstract Convenient syntheses for two 1,1,3-trisubstituted naphtho[2,3-c]pyranquinones have been developed. Alkylation of acetyl and trifluoroacetyl naphthoquinones afforded the target pyranquinones in a one-pot reaction.

The synthesis of 1,4,5,7-teetraoxygenated naphthalenes is described, as well as their selectiveacylation at either C-3 or C-8 using either trifluoroacetic anhydride or acetic acid and trifluoroacetic anhydride; the potential of these reactions in the synthesis of naturally occurring naphthoquinones is referred to.
