Concerning the structure of islandoquinone isolated from the lichen Cetraria islandica

An investigation of the oxidative coupling products of some substituted hydroxynaphthazarins led to a revision of the proposed structure of islandoquinone, previously isolated from the lichen Cetraria islandica, and yielding (7aS*, 13aS*)-6,7a-diethyl-2,5,9,11,12,13a-hexahydroxy-7, 4-dioxabenzo[a]te...
