The key steps in the synthesis of clavulactone are formation of an enantiopure cyclopentane precursor by epoxide rearrangement and intramolecular carbonyl–ene reaction, construction of the 3,4‐dihydro‐2H‐pyran ring by intermolecular hetero‐Diels–Alder reaction, closure of the eleven‐membered ring, and finally generation of the lactone functionality by chemoselective allylic C(sp3)H oxidation.
