The syntheses of multiply 13 C-labelled derivatives of the two mammalian lignans, enterolactone and enterodiol, and two of their plant lignan precursors, secoisolariciresinol and matairesinol, are described. Three 13 C atoms were incorporated into each lignan using potassium [ 13 C]cyanide as the so

## Abstract We prepared deuterium‐labeled 5‐deoxystrigol (5DS), a multifunctional plant second metabolite, using a simple set of procedures. The labeled compound contained mainly [3a,4,4,5,5,6′‐D~6~]‐5DS and [D~5~]‐5DS and did not contain unlabeled 5DS. Therefore, multideuterated 5DS can be used as
