%X 2,5-Dichloro-6-O-methylnorlichexanthone (8) (2,5-dichloro-1,3-dihydroxy-6-methoxy-8-methyl-9H-xanthen-9-one) and 4,5-dichloro-6-O-methylnorlichexanthone (9)(4,5-dichloro-1,3-dihydroxy-6-methoxy-8-methyl-9H-xanthen-9-one) have been synthesized and shown to co-occur with norstictic acid, connorstictic acid, atranorin, 6-O-methylarthothelin (4), 2,4,5- trichlorolichexanthone (5), 1,3,6-tri-O-methylarthothelin (6) and thiophaninic acid (7) in an Australian Dimelaena lichen.
