Terphenyls atromentin

Terphenyls bearing six oxygenated functions atromentin and analogues... 

Very recently, ganbajunin A (28), a further orange pigment related to atromentin, the methoxy atromentin 22 and other fully aromatic p-terphenyls (reported here in the following) were isolated from fruiting bodies of the Chinese mushroom Thelephora ganbajun [57],... 

Coloress storage forms of the long-known terphenyl-quinone atromentin from the toadstool Paxillus atro-tomentosus (Basidiomycetes). L. are esters of leuco-atromentins with (2Z, 4S,55)-4,5-epoxy-2-hexenoic acid that are cleaved under the action of alkali and ox-... 

The isolation of polyporic acid (11) [Stahlschmidt, 1877 (597, 592)], atromentin (13) [Thorner, 1878 (653)] and thelephoric acid (16) [ZOPF, 1889 (730)] marked the start of the chemical investigation of fungal pigments. The structure elucidation and chemistry of these compounds has been amply covered in Thomson s book (655) and does not need to be repeated here. In recent years several papers dealing with ultraviolet (311), infrared (208) and mass spectra (304, 465) and with the chromatography (267) and detection (274) of simple terphenyl-quinones have been published. Details of their known distribution in fungi are given in Table 3 and their physical properties are summarised in Table 4.
