  The application of chiral sulfinamides and achiral sulfonic acids as a cocatalyst system for enantioselective protonation reactions is described. Structurally simple, easily accessible sulfinamides were found to Induce moderate-to-high ee's in the formation of 2-aryl-substituted cycloalkanones from the corresponding trimethylsilyl enol ethers.

  The invention relates to new ligands that are used in a palladium source catalyst system and in palladium catalyzed method for asymmetric α-(hetero)arylation and a-vinylation of ketones. The invention further relates to a process for preparing an asymmetric α-(hetero)arylated or a-vinylated ketone which comprises reacting the tin enolate of the ketone in the presence of catalyst system comprising a ligand of the invention and palladium source. By means of the ligands and process of the invention a stereogenic center in position a of the ketone is established with high enantiomeric excess.
