文摘The double oxidative coupling of methyl 8-bromo-3,4-dihydro- xy-5,7-dimethoxy-2-naphthylacetate and its solvent effect are studied. Demethylation followed by methylation or vice versa of dimethyl-2,11-dihy- droxy-4,6,7,9-tetramethoxy-3,10-perylenequinone-1,12-diacetate can be effected regioselectively and amenable to natural product synthesis.
