Ruthenium-Catalyzed Asymmetric Transfer Hydrogenation of Sulfinylimines

Significance

Achiral β-amino alcohols were used as ligands in the ruthenium-catalyzed asymmetric transfer hydrogenation of sulfinylimines. Using both sulfinylimine enantiomers, the authors found that chirality was retained, suggesting the diastereoselectivity is controlled by the sulfinyl group, not the alcohol ligand.
