An efficient Rh-catalyzed addition of arylboronic acids to N-tosylarylimines has been developed with chiral benzene backbone-based sulfoxide-olefin ligands, where 2-methoxy-1-naphthyl sulfinyl functionalized olefin ligands have shown to be more effective.

Asymmetric reductive amination of poorly nucleophilic sulfonamides was realized in the presence of nickel catalysts and titanium alkoxide. A wide range of ketones, including enolizable ketones and some biaryl ones, were converted into sulfonamides in excellent enantiomeric excess. The cyclization of sulfamates and intermolecular reductive amination of a diarylphosphinamide were also successful. Formic acid was used as a safe and economic surrogate of high-pressure hydrogen gas.
