Claisen rearrangement of allyl vinyl ethers is one of the most powerful tools for stereoselective carbon-carbon bond formation. 1 The stereoselective formation of the enol ether moiety is the key to diastereocontrol over the newly created chiral centers of the product. However, acyclic enol ether Claisen rearrangement shows no significant diastereoselectivity because of the lack of stereoselective synthesis of the enol ether ...
