Two closely related routes to dimethyl 3,10-dihydro-2,11-di-hydroxy-4,6,7,9-tetramethoxy-3,10-dioxo-1,12-perylenediacetate (10), one involving Ullmann phenol coupling and the other by double oxidative coupling are described. Regioselective demethylation of 10 followed by methylation or vice versa yields dimethyl 3,10-dihydro-4,9-dihydroxy-2,6,7,11-tetrame-thoxy-3,10-dioxo-1,12-perylenediacetate (22) which, except for its side chains, structurally resembles some of the natural perylenequinones.Chemistry, MultidisciplinarySCI(E)6ARTICLE135-4
