A concise and highly enantioselective (>99% ee) synthesis of falcarinol and panaxjapyne A and their enantiomers has been accomplished. The key steps involve the asymmetric addition of alkynylzinc reagent to acrolein and propionaldehyde catalyzed by a BINOL-Ti(OiPr)(4) complex and a classic Cadiot-Chodkiewicz cross-coupling reaction. The chiral polyacetylenic alcohols synthesized herein have potential utility in the development of antitumor drugs and antidiabetic agents. (C) 2015 Elsevier Ltd. All rights reserved.
