文摘

Diazo transfer reactions on Behera’s amine and its next-generation analogue formed G0 and G1 azide dendrons bearing three and nine tert-butyl-protected esters, respectively. The utility of the new dendrons was demonstrated by copper-catalyzed azide–alkyne cycloaddition, with 1,3,5-triethynylbenzene, forming two novel dendrimers in a convergent manner. Acid-mediated dendrimer deprotection was successful, and the resulting carboxy-terminated dendrimers were analyzed by NMR and DOSY experiments.
