The design and development of a novel class of chiral sulfur–olefin hybrid ligands with high synthetic feasibility are described. These new sulfoxide–olefin ligands showed excellent catalytic activities and enantioselectivities (up to 98% ee) in rhodium-catalyzed asymmetric 1,4-addition reactions of aryl boronic acids to α,β-unsaturated carbonyl compounds.
