Abstract
A simple method for making EDTA, ED3A or DTPA analogs from amide derivatives of alpha amino acids is disclosed. These EDTA, ED3A or DTPA analogs are useful chelating agents, and preferably are useful as bifunctional chelating agents which may be attached to biological molecules and which form physiologically stable chelates with a variety of metal ions.
