  Enantioselective Synthesis of (Z)-1,2-anti-2,5-anti-Triol Monosilyl Ethers Using a Cross-Metathesis Allylboration Sequence

  摘要：

  The enantioselective synthesis of (Z)-1,2-anti-2,5-anti-triol monosilyl ethers via a two-step sequence involving olefin cross-metathesis of beta-alkoxyallylboronate 4 and subsequent allylboration of the derived bisboryl intermediate 6 provides triol monoethers 7 with good to excellent diastereoselectivity.
