摘要

Abstract Gentisic acid reacted with methyl iodide in HMPA to give 94% of the corresponding methyl ester. Its oxidation with Ag 2 O in toluene afforded 57% of methoxycarbonylbenzoquinone as yellow crystals. Reaction of the latter with cyclopentadiene resulted in formation of methyl 3, 6-dioxotricyclo [6.2. 1.02, 7] undeca-4, 9- diene-2-carboxylate (21%).
