Copper-free click chemistry protocol
WebWe illustrate the efficiency of the copper-free click reaction using 6-HEX Azide, one of two additions to our selection of azides for click chemistry, in Figure 5. Use of DBCO-sulfo … 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…
