  Synthesis of the dysiherbaine tetrahydropyran core utilizing improved tethered aminohydroxylation conditions

  摘要：

  A concise stereoselective route to the dysiherbaine tetrahydropyran core was achieved in nine steps and 39% overall yield. Donohoe's improved tethered aminohydroxylation conditions were employed to concurrently install the amino and alcohol groups and construct the tetrahydropyran ring, which features four contiguous cis-stereocenters.
