The structure determination of thiomelin (2,4-dichloro-1,8-dihydroxy-5-methoxy-6-methyl-9H-xanthen-9-one) (3), an unusual lichen metabolite probably derived biosynthetically by oxidative ring opening of a precursor anthraquinone, is reported. The cry

Reaction of acetic anhydride- perchloric acid with 3-oxoolean-12-en-29- oic acid (4) gave either the enol acetate (6) or the derived γ- pyrono compound (8). The structure assigned to the latter was confirmed by a single-crystal X-ray structure deter

An equilibrium mixture of the isomeric depsides para- and meta- scrobiculin has been extracted from the lichen Lobaria scrobiculata. Acetylation of this mixture led to the isolation of two isomeric triacetates, the structures of which were confirmed
