The synthesis of a new rigid analogue of cyclohexyl-TTHA, an efficient lanthanide ligand, as well, as the first complexation trials are reported. This polyaminopolycarboxylic acid, Ph-DTHA 1, was obtained in five steps from phenylenediamine as starting product. The key intermediate was phenylenediethylenetetraamine 4, which after alkylation and hydrolysis gave the expected compound 1 with ten coordination centers.

We wish to report the synthesis and metal complexation properties of new radionuclide chelating agents for use in nuclear medicine. The strategy includes the facile preparation of rigid analogues of DTPA and TTHA possessing an aromatic ring. The aromatic structure used increased the stability of the complexes formed (pre-organization concept) and they are easily functionalised for attaching to any
