Palladium-catalyzed allylic alkylation of optically active α-alkenyl-α-acyloxytrialkylsilane

Pd-catalyzed inter- and intramolecular allylic alkylations of optically active α-alkenyl-α-acyloxysilanes are described. The reactions proceeded in a regio- and stereoselective manner to give the corresponding (E)-vinylsilanes in which the ee of the starting material was completely transferred to the product.
