The depsidones phyllopsorin (2-chloro-4,6-diformyl-3-hydroxy-8-methoxy-1,9-dimethyl-11H-dibenzo(1,4>dioxepin-11-one (3), chlorophyllopsorin (2,7-dichloro-4,6-diformyl-3-hydroxy-8-methoxy-1,9-dimethyl-11H-dibenzodioxepin-11-one) (4), methyl 2,7-dichloropsoromate (methyl 2,7-dichloro-4-formyl-3-hydroxy-8-methoxy-1,9-dimethyl-11-oxo-11H-dibenzodioxepin-6-carboxylate) (5) and methyl 2,7-dichloronorpsoromate (methyl 2,7-dichloro-4-formyl-3,8-dihydroxy-1,9-dimethyl-11-oxo-11H-dibenzodioxepin-6-carboxylate) (6) have been isolated from the lichen Phyllopsora corallina var. ochroxantha.The structures of these metabolites have been established from the spectroscopic properties, degradative studies and by partial synthesis.
