✦ Synopsis

New simplified syntheses of two natural p‐diquinonic pigments, phoenicine and oosporeine, have been described. By similar procedures, the syntheses of two other related diquinones have been carried out: 3,3′,6,6′‐tetrahydroxy‐biphenyl‐di‐p,p′‐quinone and 3,3′,6,6′‐tetrahydroxy‐4‐methyl‐biphenyl‐di‐p,p′‐quinone. The latter structure had been assigned to pyxiferine, which had been reported to be contained in the lichen Pyxine coccifera.

The biosynthesis of phoenicine and of oosporeine by intact cells of __Penicillium phoeniceum__ VAN BEYMA and of __Chaetomium aureum__ CHIVERS respectively, has been investigated. Starting from acetic acid, biosynthetic sequences have been proposed; they are based on the incorporation of radioactivit
