Concise enantioselective eleven-step syntheses leading to (―)- and (+)-trans-whiskylactones were developed. Propargyl alcohol was employed as starting material. The reaction sequences include highly diastereoselective electrophilic cyclization of γ-allenoic acids, dehydroiodination, and hydrogenation.
