Abstract
Herein, we present an easy and efficient synthesis of amino terminal dendrons, combining protection/deprotection reactions with copper-catalyzed azide alkyne cycloaddition in a convergent way. This new approach affords dendrons in gram scale with excellent yields and easy purification. By choosing the appropriate azido-functionalized core, these dendrons lead to a more efficient and controlled convergent synthesis of dendrimers with different sizes and shapes and multivalence. The amino terminal dendrimers were analyzed by diffusion-ordered spectroscopy experiments. The observed dendrimer size is in excellent correlation with the expected size and shape by molecular dynamic simulations. The construction of these kinds of nanostructures, in a simple and efficient way, opens new opportunities for biomedical applications. Moreover, by choosing the appropriate core, these versatile macromolecules become an excellent fluorescent biomarker.

Abstract
2,2-Bis(azidomethyl)propionic acid was prepared in four steps and 85% yield from the commercially available 2,2-bis(hydroxymethyl)propionic acid and used as the starting building block for the divergent, convergent, and double-stage convergent-divergent iterative methods for the synthesis of dendrimers and dendrons containing ethylenediamine (EDA), piperazine (PPZ), and methyl 2,2-bis(aminomethyl)propionate (COOMe) cores. These cores have the same multiplicity but different conformations. A diversity of synthetic methods were used for the synthesis of dendrimers and dendrons. Regardless of the method used, a self-interruption of the synthesis was observed at generation 4 for the dendrimer with an EDA core and at generation 5 for the one with a PPZ core, whereas for the COOMe core, self-interruption was observed at generation 6 dendron, which is equivalent to generation 5 dendrimer. Molecular modeling and molecular-dynamics simulations demonstrated that the observed self-interruption is determined by the backfolding of the azide groups at the periphery of the dendrimer. The latter conformation inhibits completely the heterogeneous hydrogenation of the azide groups catalyzed by 10% Pd/carbon as well as homogeneous hydrogenation by the Staudinger method. These self-terminated polyamide dendrimers are enzymatically and hydrolytically stable and also exhibit antimicrobial activity. Thus, these nanoscale constructs open avenues for biomedical applications.
