[phenyl-13C6]Lachnanthocarpone ([phenyl-13C6]2,6-dihydroxy-9-phenylphenalen-1-one), a hypothetical intermediate in the biosynthesis of various natural phenylphenalenones, was prepared in four steps using [U-13C]bromobenzene to introduce the label. Based on related methodologies further native phenylphenalenones such as [phenyl-13C6]anigorufone, [1-13C]anigorufone and [4′-O13CH3]4′-methoxyanigorufone were synthesized in labelled form.
