The structure of the lichen depsidone hydroxyphysodic acid. A carbon-13 magnetic resonance study
, 1976 Unequivocal evidence for the structure of the lichen depsidone 3-hydroxyphysodic acid has been provided by analysis of long-range carbon-13-hydrogen coupling interactions and carbon-13 chemical shifts.

3-Hydroxyphysodic acid. Chemical corroboration of the structure of this lichen depsidone
, 1976 The published structure of the lichen depsidone ?physodol? has been shown to be incorrect. This compound is in fact identical with 3- hydroxyphysodic acid (2) (1?-carboxy-2?,3,4-trihydroxy-6-(2?- oxoheptyl)-6?-pentyldepsidone).

, 1987 The structurally unique depsidone furfuric acid (1) has been prepared in one step by the acid-catalysed alkylation of methyl p- orsellinate (6) or of atranorin (4) with physodalic acid (7). This mode of synthesis gives credence to the proposal that

Chemistry of Australian Lichens. II. A New Depsidone from Parmelia conspersa (Ehrh.) Ach
, 1960 A new compound, norlobaridone, from Parmelia conspersa is shown to have structure Ia by conversion of its monomethyl ether (lobaridone (Ib)) into lobariol (IIb).
