Copper(I)-catalyzed 1,3-dipolar cycloaddition reaction of nonfluorescent 3-azidocoumarins and terminal alkynes afforded intense fluorescent 1,2,3-triazole products. The mild condition of this reaction allowed us to construct a large library of pure fluorescent coumarin dyes. Since both azide and alkyne are quite inert to biological systems, this reaction has potential in bioconjugation and bioimaging
铜(I)催化的非荧光3-azidocoumarins和末端炔烃的1,3-偶极环加成反应可提供强烈的荧光1,2,3-三唑产物。此反应的温和条件使我们能够构建一个大型的纯荧光香豆素染料库。由于叠氮化物和炔烃对生物系统都非常惰性,因此该反应在生物共轭和生物成像应用中具有潜力。[反应:看文字]
