Reactions of Unsaturated Azides; Part 22: [¹] The Alkyne Azide Click Chemistry as a Synthetic Tool for the Generation of Cage-Like Triazole Compounds

Abstract

The applicability of the copper(I)-catalyzed click reaction of terminal trialkynes with triazides to the synthesis of cage-like triazole compounds was determined. A number of starting materials were prepared and several monotriazoles as well as macrocyclic bistriazoles were obtained from the triazide trialkyne reaction. Finally, a tristriazole macrobicyclic compound was synthesized from the previously formed triazole precursors.

Key words

triazoles - cycloadditions - azides - alkynes - click chemistry
