  Enantioselective Total Synthesis of Eicosanoid and Its Congener, Using Organocatalytic Cyclopropanation, and Catalytic Asymmetric Transfer Hydrogenation Reactions as Key Steps

  摘要：

  An enantioselective unified strategy for the syntheses of the oxylipin class of natural products was accomplished. Our strategy relies on three catalytic steps: (a) organocatalytic cyclopropanation, (b) the catalytic asymmetric transfer hydrogenation (CATHy) reaction, and (c) the Nozaki-Hiyama-Kishi reaction.
