Abstract

Abstract An enantioselective synthesis of tetrasubstituted α-phosphono-α-amino nitriles through asymmetric cyanation of α-ketiminophosphonates catalyzed by Cinchona alkaloids is reported. α-Ketiminophosphonates are generated, in a very efficient synthetic protocol, by oxidation of trisubstituted α-aminophosphonates.
