title: Dynamic kinetic resolution of beta-keto sulfones via asymmetric transfer hydrogenation.
abstract: The dynamic kinetic resolution of beta-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 yield with up to >99 : 1 dr and high ee up to >99%.
