Chiral ruthenium(II) complexes modified by josiphos ligands catalyze the reaction of alkyhes With primary alcohols to form homoallylic alcohols with excellent control of regio-, diastereo-, and enantio-selectivity. These processes represent the first examples of enantioselective carbonyl allylation using alkynes as allylmetal equivalents.
