Abstract
The depside 3-chloro-4-O-demethylmicrophyllinic acid
[4-{3′-chloro-2′,4′-dihydroxy-6′-(2′″-oxoheptyl)benzoyl-oxy}benzoic
acid] (2) has been isolated from the lichen
Hypotrachyna leiophylla together with atranorin,
chloroatranorin and 4-O-demethylmicrophyllinic acid (1).
The compound (2) was characterized as the corresponding
p-nitrobenzyl ester, the structure of which followed
from a combination of spectroscopic and degradative evidence.
