✦ Synopsis

Various dithioureas bearing an aromatic ring on their terminal nitrogen atoms have been synthesized. These have been tested in the asymmetric reduction of ketones as catalyzed by a rhodium complex. The influence of electron-withdrawing and electron-donating substituents on the aromatic rings on the reactivity and the enantiomeric excess (ee) has
