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 source, affording various optically pure vicinal stereocenters β-hydroxy sulfones in high yields with excellent enantioselectivities (up to 99%) and diastereomeric ratios (up to 99:1) under mild reaction conditions.

The dynamic kinetic resolution of β-keto sulfones was achieved via asymmetric transfer hydrogenation using (S,S)-RuCl[N-(tosyl)-1,2- diphenylethylenediamine](p-cymene) in the presence of formic acid and triethylamine afforded the desired products in good
