New chiral β-amino sulfoxide ligands bearing chiral sulfinyl functionality as a sole chiral source have been deviced and palladium-catalyzed asymmetric allylations of acetoacetate with these ligands have been examined. The highest enantioselectivity (50%) was observed with 5b. The participation of chual sulfinyl functionality to palladium catalysts is discussed on the basis of the stereochemical outcome obtained.
