Chelating ligands functionalized for facile attachment to biomolecules. A convenient route to 4-isothiocyanatobenzyl derivatives of diethylenetriaminepentaacetic acid and ethylenediaminetetraacetic acid

The title compounds were synthesized by alkylation of the monoenolates of DTPA and EDTA permethyl esters 3 and 4 with benzyl bromide. The benzylated esters 5 and 6 were nitrated, hydrogenated, and converted to their isothiocyanate derivatives 13 and 14 in
