Strategic application of CuAAC click chemistry in the modification of natural products for anticancer activity

open access: yesEuropean Journal of Medicinal Chemistry Reports, 2023
Natural products play a key role in the history of human drug discovery, and especially for the anticancer agents. Copper(I)-catalyzed alkyne-azide [3+2] cycloaddition (CuAAC) reaction is perhaps the most powerful method for the efficient modification of

Resin-Supported Catalysts for CuAAC Click Reactions in Aqueous or Organic Solvents [PDF]

open access: yesACS Combinatorial Science, 2012
The copper-catalyzed azide-alkyne cycloaddition click reaction is a valuable process for the synthesis of libraries of drug candidates, derivatized polymers and materials, and a wide variety of other functional molecules. In some circumstances, the removal of the copper catalyst is both necessary and inconvenient. We describe here two immobilized forms
