  10. 1st Generation Click Chemistry

    Azido and alkyne functions can cyclise by an intramolecular CuI or Cu0 catalyzed azide-alkyne 1,3-dipolar cycloaddition (CuAAC). This so-called Click Reaction, developed by K. Barry Sharpless and Morton Meldal, has meanwhile grown to a widely used type of reaction orthogonal to many other types of reactions in different kinds of applications.
