A synthesis of various amino phosphonates has been achieved via phosphonate substituted carbene insertion into the N-H bond of aniline catalyzed by readily available copper salt under mild reaction conditions in water. Using this environmentally benign methodology a large number of biologically important amino phosphonates have been synthesized in good isolated yields.
