The synthesis of dimethyl 2-acetoxy-2-(2,4-diiodo-5-aminophenyl)ethylphosph
onate and dimethyl 2-acetoxy-2-(2,4,6-triiodo-3,5-diaminophenyl)ethylphosph
onate is described. Several amido and peptidic derivatives of these two com
pounds were prepared. These products are composed of a combination of struc
tural/functional moieties which pave the way for their potential applicatio
n as non-ionic selective X-ray contrast agents.
