  Synthetic studies on zoapatanol: Construction of oxepanes via an intramolecular 1,3-dipolar cycloaddition strategy

  摘要：

  The nitrones derived from beta-allyloxyaldehydes with a beta-quaternary centre cyclized to give six- instead of seven-membered O-heterocycles exclusively whereas a nitrile oxide derived from a gamma-allyloxyaldehyde with a gamma-quaternary centre cyclized to yield an oxepane ring as the sole product. Using the latter intramolecular nitrile oxide cycloaddition as the key step, optically active oxepane 5, which is a suitable intermediate for a synthesis of zoapatanol 1, has been constructed from D-glucose.
