Click chemistry

Modular approach to chemical synthesis

Click chemistry is an approach to chemical synthesis that emphasizes efficiency, simplicity, selectivity, and modularity in chemical processes used to join molecular building blocks. It includes both the development and use of "click reactions", a set of simple, biocompatible chemical reactions that meet specific criteria like high yield, fast reaction rates, and minimal byproducts. It was first fully described by Sharpless, Hartmuth C. Kolb, and M. G. Finn of The Scripps Research Institute in 2001. In this seminal paper, Sharpless argued that synthetic chemistry could emulate the way nature constructs complex molecules, using efficient reactions to join together simple, non-toxic building blocks.
