Abstract

The synthesis of 4-acetoxy-1,8-dihydroxy-2-methyl-3-(4-methylpentanoyl)phenanthrene-9,10-quinoee (30) and 1,4,8-trimethoxy-2-methyl-3-(4-methylpentanoyl)phenanthrene-9,10-quinone (33), derivatives of the mould metabolite 4-hydroxypiloquinone [1,4,8-trihydroxy-2-methyl-3-(4-methylpentanoyl)-phenanthrene-9,10-quinone](2) are described. Photocyclization of methyl 2,2′,5,6′-tetramethoxy-3-methylstilbene-4-carboxylate (21) provided methyl 1,4,8-trimethoxy-2-methylphenanthrene-3-carboxylate (22), suitable for further elaboration into the natural derivatives.
