  2. Click chemistry - Wikipedia

    en.wikipedia.org/wiki/Click_chemistry

    Click chemistry is an approach to chemical synthesis that emphasizes efficiency, simplicity, selectivity, and modularity in chemical processes used to join molecular ...

  3. Karl Barry Sharpless - Wikipedia

    en.wikipedia.org/wiki/Karl_Barry_Sharpless

    The term "click chemistry" was coined by Sharpless around the year 2000, and was first fully described by Sharpless, Hartmuth Kolb, and M.G. Finn at The Scripps Research Institute in 2001. [ 11 ] [ 2 ] This involves a set of highly selective, exothermic reactions which occur under mild conditions; the most successful example is the azide alkyne ...

  4. Azide-alkyne Huisgen cycloaddition - Wikipedia

    en.wikipedia.org/wiki/Azide-alkyne_Huisgen_cyclo...

    A notable variant of the Huisgen 1,3-dipolar cycloaddition is the copper(I) catalyzed variant, no longer a true concerted cycloaddition, in which organic azides and terminal alkynes are united to afford 1,4-regioisomers of 1,2,3-triazoles as sole products (substitution at positions 1' and 4' as shown above).

  5. Thiol-ene reaction - Wikipedia

    en.wikipedia.org/wiki/Thiol-ene_reaction

    In organosulfur chemistry, the thiol-ene reaction (also alkene hydrothiolation) is an organic reaction between a thiol (R−SH) and an alkene (R 2 C=CR 2) to form a thioether (R−S−R'). This reaction was first reported in 1905, [ 1 ] but it gained prominence in the late 1990s and early 2000s for its feasibility and wide range of applications.

  6. Copper-free click chemistry - Wikipedia

    en.wikipedia.org/wiki/Copper-free_click_chemistry

    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. [ 1 ]

  7. Bioorthogonal chemistry - Wikipedia

    en.wikipedia.org/wiki/Bioorthogonal_chemistry

    Copper-free click chemistry is a bioorthogonal reaction first developed by Carolyn Bertozzi as an activated variant of an azide alkyne Huisgen cycloaddition, based on the work by Karl Barry Sharpless et al. Unlike CuAAC, Cu-free click chemistry has been modified to be bioorthogonal by eliminating a cytotoxic copper catalyst, allowing reaction ...

  8. Bicyclononyne - Wikipedia

    en.wikipedia.org/wiki/Bicyclononyne

    BCN, with free hydroxymethyl group. BCN, also known as bicyclo[6.1.0]non-4-yne, is a copper-free click chemistry probe that enables highly efficient and completely orthogonal bioconjugation to complex macromolecules including peptides, nucleic acids and proteins, including monoclonal antibodies.

  9. Chemistry - Wikipedia

    en.wikipedia.org/wiki/Chemistry

    Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
