An efficient stereoselective total synthesis of the bioactive 14‐membered natural macrocyclic bislactone 4‐ketoclonostachydiol is described. The strategy involves a Jacobsen 's hydrolytic kinetic resolution (HKR), epoxide opening, MacMillan α ‐hydroxylation, Horner Wadsworth Emmons olefination, a Grignard reaction, and Hoveyda Grubbs ‐ II ‐catalyzed ring‐closing metathesis (RCM) as key steps.
