useful linchpin in an efficient three-component coupling process. The reaction features a [1,4]-Brook rearrangement to generate the silylallyl anion, which adopts a predominant endo-orientation and can undergo addition to electrophiles in a regio- and stereoselective manner, giving various E-vinylsilane species in good yields.
