Ru-catalyzed asymmetric hydrogenation of α-substituted α,β-unsaturatedketones has been developed for the enantioselective synthesis of chiral α-substituted secondary alcohols with high diastereo- and enantioselectivities (up to >99 : 1 dr, 98% ee). Mechanistic experiments suggest that the reaction proceeds via a Ru-catalyzed asymmetric hydrogenation of the CO bond in concert with a base-promoted allylic

Potassium trifluoroboratoketohomoenolates were prepared in good yields from either the corresponding alpha,beta-unsaturated compounds or methyl ketones. These organoboron reagents were effectively cross-coupled with various aryl and heteroaryl chlorides.

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.
