Synthesis of Tetrasubstituted α‐Aminophosphonic Acid Derivatives from Trisubstituted α‐Aminophosphonates

Abstract

AbstractAn efficient method for the preparation of quaternary α‐aminophosphonic acid derivatives is reported. The nucleophilic addition of organometallic reagents to α‐ketiminophosphonates allows the preparation of quaternary α‐aminophosphonates. The diastereoselective synthesis of a quaternary α‐aminophosphonate using a chiral tartaric‐acid‐derived phosphonate is also described.
