A new stereoselective synthesis of (Z)-vinylsilane allylic alcohols

A new, highly stereoselective method for the synthesis of (Z)-vinylsilane allylic alcohols 3 is described. This approach to such γ-silylated allylic alcohols employs a novel 1,4-0→sp2C silyl rearrangement of appropriate silyl ether precursors 2.
