Abstract
By stepwise modification of gallic acid using an azide-alkyne cycloaddition reaction, a first-generation triazole-containing dendron with hydroxypropyltriazole groups and a tetraethylene glycol linker was obtained for the first time. The structure of all intermediate compounds has been proven by modern physical methods. It has been established that the use of bromomethylene derivatives of gallic acid in the synthesis of triazole-containing dendrons results in the formation of by-products of alkylation of the bases used in the reaction (triethylamine and diisopropylethylamine) due to the high mobility of the bromine atom in the benzyl position.
