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.
