  1. Organized by Tai-Shan Fang, For Special Advance Physical Organic Chemistry

  2. "click chemistry" In the "click chemistry" strategy developed recently at Scripps Research Institute, reactive molecular building blocks are designed to "click" together selectively and covalently. The Scripps researchers are now extending the idea by using protein binding sites, supramolecular complexes, or functionalized surfaces as reaction vessels to direct the in situ formation of potentially functional click chemistry products. The products might be biological inhibitors, molecular-electronics components, sensor probes, nonlinear optical materials, light-harvesting compounds, or compounds with any number of other useful properties.

  8. Mirror Image Catalysis • Many molecules appear in two forms that mirror each other – just as our hands mirror each other. Such molecules are called chiral. In nature one of these forms is often dominant, so in our cells one of these mirror images of a molecule fits "like a glove", in contrast to the other one which may even be harmful. Pharmaceutical products often consist of chiral molecules, and the difference between the two forms can be a matter of life and death – as was the case, for example, in the thalidomide disaster in the 1960s. That is why it is vital to be able to produce the two chiral forms separately. • This year's Nobel Laureates in Chemistry have developed molecules that can catalyse important reactions so that only one of the two mirror image forms is produced. The catalyst molecule, which itself is chiral, speeds up the reaction without being consumed. Just one of these molecules can produce millions of molecules of the desired mirror image form. • William S. Knowles discovered that it was possible to use transition metals to make chiral catalysts for an important type of reaction called hydrogenation, thereby obtaining the desired mirror image form as the final product. His research quickly led to an industrial process for the production of the L-DOPA drug which is used in the treatment of Parkinson's disease. Ryoji Noyori has led the further development of this process to today's general chiral catalysts for hydrogenation. • K. Barry Sharpless, on the other hand, is awarded half of the Prize for developing chiral catalysts for another important type of reaction – oxidation. • The Laureates have opened up a completely new field of research in which it is possible to synthesise molecules and material with new properties. Today the results of their basic research are being used in a number of industrial syntheses of pharmaceutical products such as antibiotics, anti-inflammatory drugs and heart medicines.

  10. thalidomide disaster Chemistry Thalidomide (α-phthalimidoglutarimide) has a chiral centre and was dispensed as a racemate (1:1 mixture) of dextrorotatory (R)- and levorotatory (S)-thalidomide. Initial animal studies indicated that the enantiomers have different biological properties: Calming and sleep-inducing effects are associated with the R-enantiomer, whereas teratogenic effects are more closely associated with the S-enantiomer. Under physiological conditions, both enantiomers undergo rapid interconversion making a total separation of their clinical effects unfeasible. • Thalidomide (Contergan) - Annotated Collection of Links Annotated collection of English and German web resources providing information on the drug's physico-chemical properties, effects, side effects, the German Contergan disaster in the early 1960s, and the current use of thalidomide.
