Cover Picture: Architecture and Evolution of Organic Chemistry (Angew. Chem. Int. Ed. 44/2005)
Organic synthetic reactions are treated as a connected network so that the mechanism by which organic chemistry evolved can be studied. In their Communication on page 7263 ff., B. A. Grzybowski and co-workers analyze organic syntheses reported between 1850 and 2004, thus revealing the architecture and evolution of the synthesis of molecules, and discuss the application of this technique to the chemical industry. The cover picture shows a typical “hub” in a network of organic chemistry.
