Enantioselective synthesis of (R)-deoxydysibetaine and (- )-4-epi-dysibetaine

Abstract Enantioselective synthesis of ( R )-deoxydysibetaine and (−)-4- epi -dysibetaine was achieved by employing a samarium iodide-promoted reductive carbon–nitrogen bond cleavage of a proline derivative, as a key reaction.
