WebFeb 18, 2024 · Here, we exploited a copper-free Huisgen cycloaddition for template synthesis using a peptide fragment containing a 4,8-diazacyclononyne (DACN) moiety … Copper-free click chemistry is a bioorthogonal reaction as a variant of an azide-alkyne Huisgen cycloaddition. By eliminating cytotoxic copper catalysts, the reaction proceeds without live-cell toxicity. It was developed as a faster alternative to the Staudinger ligation with the first generation of Cu-free click chemistry, producing rate constants over 63 times faster. Although the reaction produces a regioisomeric mixture of triazoles, the lack of regioselectivity i…
