Finely-tuned ruthenium-catalyzed highly chemoselective and enantioselectivehydrogenation of gamma-halo-gamma,delta-unsaturated-beta-keto esters at the carbonyl group was achieved under neutral reaction conditions (ee up to 97%). Both olefin and alkenyl halogen moieties, which are labile underhydrogenationconditions, remained untouched during the reaction.
