Abstract

[phenyl‐^13^C~6~]Lachnanthocarpone ([phenyl‐^13^C~6~]2,6‐dihydroxy‐9‐phenylphenalen‐1‐one), a hypothetical intermediate in the biosynthesis of various natural phenylphenalenones, was prepared in four steps using [U‐^13^C]bromobenzene to introduce the label. Based on related methodologies further native phenylphenalenones such as [phenyl‐^13^C~6~]anigorufone, [1‐^13^C]anigorufone and [4′‐O^13^CH~3~]4′‐methoxyanigorufone were synthesized in labelled form.
