The key step in this total synthesis of (−)‐acetylaranotin is the efficient formation of the characteristic dihydrooxepine ring from cyclohexenone through an unusual vinylogous Rubottom oxidation and a regioselective Baeyer–Villiger oxidation. (−)‐Acetylaranotin is obtained in 22 steps from commercially available L ‐Cbz‐tyrosine (Cbz=benzyloxycarbonyl).
