Bacterial naphthoquinone meroterpenoid natural products defy biosynthetic logic via classical biochemical paradigms. Now, an enzyme promoted α-hydroxyketone rearrangement catalysed by vanadium-dependent haloperoxidases reveals a conserved biosynthetic reaction in this molecular class that further has inspired a concise biomimetic synthesis of naphthomevalin, a prominent member of the napyradiomycin meroterpenes.
