A noval method for the synthesis of optically active β-hydroxy sulfones was developed. Through a substitution/dynamic kinetic resolution–asymmetric transfer hydrogenation, the presented method was based on one-pot enantioselective organic transformations of α–bromoindenones and sodium arylsulfinate. The protocol employed RuCl2[(S,S)–TsDPEN](mesitylene) as a catalyst, and sodium formate as a hydrogen
