  Enantioselective Synthesis of α,β,α‘-Trisubstituted Cyclic Ethers

  摘要：

  A synthetic strategy for the preparation of trisusbstituted cyclic ethers is presented, in which the stereochemistry at the carbon atoms adjacent to the oxygen of the ether was controlled by means of a hetero Diels-Alder reaction between a monoactivated diene and a chiral aldehyde. The adducts were transformed into linear ethers, which were then used for the preparation of cis and trans cyclic ethers of different sizes. A cis-oxepane, cis-oxonane, and cis-oxocane and a trans-oxocane were prepared as examples of the scope of the strategy.
