Three New Aliphatic Acids from Lichens of Genus Parmelia (Subgenus Xanthoparmelia)
DO Chester,John A. Elix +1 more
TL;DR: The aliphatic acids, constipatic acid [2-(14'-hydroxypentadecyl)-4-methylene-5-oxotetrahydro- furan-3-carboxylic acid] and dehydroconstipatic acids [4-methy 1-5 -oxo-2-14'-oxopentadecy1)-2,5- dihydrofuran- 3-CARBOXYlic acid], have been identified as constituents of various Xanthoparmelia lichens from Australia as mentioned in this paper.

Condidymic Acid, a New Dibenzofuran from the Lichen Cladonia squamosula
DO Chester,John A. Elix +1 more
TL;DR: The dibenzofuran condidymic acid (3-hydroxy-7methoxy-1,9- dipentyldibenz-ofuran-2-carboxylic acid) has been prepared by unambiguous synthesis and shown to co-occur with barbatic, thamnolic and didymic acids in Cladonia squamosula as discussed by the authors.

The identification of four new meta-depsides in the lichen Ramalina asahinae
DO Chester,John A. Elix +1 more
TL;DR: The four new depsides, 2-O-methylsekikaic acid, 2,4'-di-o-methylnorsekikaIC acid, 4'-O-mmethyl-paludosic acid and 4,4'di-methyl-cryptochlorophaeic acid have been prepared by unambiguous syntheses and shown to co-occur with usnic acid and boninic acid in several Ramalina species as discussed by the authors.
