Enantioselective Michael addition of alpha-nitrophosphonates to enones for the synthesis of alpha-aminophosphonates is reported for the first time. The reaction proceeds in good to high yields and moderate to high selectivity in the presence of a new quinine thiourea catalyst. The quaternary nitrophosphonates were conveniently transformed to cyclic quaternary alpha-aminophosphonates via in situ reduction intramolecular cyclization or Baeyer-Villiger oxidation followed by in situ reduction intramolecular cyclization.
