Abstract
Processes for synthesizing aminosulfone compounds are provided. The processes provided herein utilize asymmetric reduction reactions, e.g., asymmetric hydrogenation, of protected or unprotected enamine or ketone substrates. Aminosulfone compounds obtained using methods provided herein are useful in production or synthesis of sulfone group containing isoindoline based compounds.
