An enantioselective total synthesis of two sesquiterpenoids, kopeolin and kopeolone, has been achieved. Using the diastereoselective addition of an organocerate as a key step, we controlled the absolute stereochemistry of a crucial stereocenter present in these natural products. This approach allowed us to confirm a structural revision that we previously proposed ( Chem.—Eur. J. 2013, 19, 10632−10642)
