steps of diazotransfer and clickchemistry reactions. The building blocks for dendron synthesis were made by incorporating monodisperse oligoethylene glycol (OEG) chains of exact length onto diethyelenetriaminepentaacetic acid (DTPA)-derived moieties to obtain first-generation dendrons. Afterward, the amine groups of the first-generation core dendron were converted to azides by means of the diazo transfer

A highly versatile synthetic strategy is described to generate multimodal and multivalent platforms based on a diethylenetriaminepentaacetic (DTPA) core. Compounds with different functionalization patterns, from mono- to pentamodal, have been prepared using robust and simple chemistry.
