Regio‐ and Stereoselective Synthesis of Fully Substituted Silyl Enol Ethers of Ketones and Aldehydes in Acyclic Systems

The regio‐ and stereoselective preparation of fully substituted and stereodefined silyl enol ethers of ketones and aldehydes through an allyl‐Brook rearrangement is reported. This fast and efficient method proceeds from a mixture of E and Z isomers of easily accessible starting materials.
