✦ Synopsis


Palladium catalyzed asymmetric allylic alkylations of a bis(trimethylsilyl) substituted propenyl acetate and carbonate were investigated using various chiral ligands and reaction conditions. The best enantioselectivity (86% e.e.) was obtained with the substrate l-phenyl-3,3-bis(trimethylsilyl)propenyl carbonate 13 and the chiral oxazoline ligand 4c.
