Nobel Connection The 2001 Chemistry Nobel Prize winner, Professor K. barry sharpless, with K.barry sharpless (Nobel Prize, asymmetric catalysis, 2001) at MIT. http://www.hkbu.edu.hk/~chem/nobel.htm
Extractions: The 2001 Chemistry Nobel Prize winner, Professor K. Barry Sharpless, was the post-doctoral research supervisor of our chemistry colleague Professor Albert Lee. All together, five scientists at HKBU had worked under the direct supervision, either as Ph.D. students or post-doctoral researchers, of a Chemistry Nobel Laureate. Four of them are from the Chemistry Department.

K. Barry Sharpless, an MIT chemistry professor for 17 years until he joined Scripps Research Institute in 1990, was chosen October 10 to share the 2001 Nobel Prize in chemistry with two other researchers. Sharpless, 60, received a Ph.D. degree in 1968 from Stanford University. Since 1990, he has been W. M. Keck Professor of Chemistry at the Scripps Research Institute. After starting his career at MIT as an assistant professor, Sharpless moved back to Stanford in 1977. Although he had started his quest for a practical catalyst for asymmetric epoxidation while at MIT, after 10 years of effort, the key breakthrough took place in January 1980 at Stanford. Sharpless decided that he wanted to return to MIT to pursue this important discovery. He and his lab moved back to MIT that summer. It was at MIT that he fully developed the process now known as the Sharpless Asymmetic Epoxidation and it was also here that he and his coworkers discovered the Sharpless Asymmetric Dihydroxylation. Sharpless left MIT in 1990 to join the Scripps Research Institute. "Barry's friends and former colleagues here at MIT are thrilled that his important contributions to chemistry have been recognized with this year's Nobel Prize in chemistry," said Rick L. Danheiser, A. C. Cope Professor and associate department head in chemistry. "Most of the work for which the prize was awarded was carried out here at MIT, where Barry was a valued colleague and a wonderful teacher and mentor for a great many students over the years."

Extractions: The Scripps Research Institute Citation: A Benjamin Franklin Medal of The Franklin Institute in the field of Chemistry is awarded to K. Barry Sharpless for his innovative contributions to the development of broadly useful and commercially viable catalytic oxidation chemistry for the selective production of bioactive molecules with the proper right or left "handedness," which allow the manufacture of safer and more effective drugs and agricultural chemicals. Summary The manufacture of safer and more effective pharmaceuticals and chemicals for a variety of applications in the life sciences demands the ability to selectively synthesize molecules of left or right "handedness." Handedness refers to the existence of pairs of chemical molecules that differ only by being mirror images of each other. The most effective way to steer a chemical reaction toward the formation of only the product of desired handedness is the use of a handed catalyst. While not being consumed in the reaction, the catalyst speeds up the formation of the desired product. In doing so repeatedly, it transfers its "handedness" to many product molecules and thus multiplies its structural information manifold. Professor K. Barry Sharpless has pioneered the discovery of three catalytic reactions that add oxygen atoms to molecules containing a carbon-carbon double bond, to selectively produce chemical compounds with the desired handedness. These processes are used extensively by academic and industrial chemists.
Extractions: NIGMS Grantee K. Barry Sharpless Wins Nobel Prize for Advances in Mirror-Image Chemistry "Dr. Sharpless' creativity has helped the entire field of chemistry produce extremely useful molecules, including many different therapeutics, that continue to improve the health and enhance the lives of all Americans," said Dr. Ruth L. Kirschstein, acting director of NIH. "This year's Nobel Prizes in Chemistry and Physiology or Medicine both beautifully underscore the value of basic biological research in yielding vital medical advances." The Royal Swedish Academy of Sciences in Stockholm announced the chemistry prize winners this morning. Dr. Sharpless, W.M. Keck Professor of Chemistry at The Scripps Research Institute in La Jolla, California, received half of this year's chemistry award for his work on "chirally catalyzed oxidation reactions." Sharing the other half of the prize for their work on "chirally catalyzed hydrogenation reactions," are Dr. William S. Knowles of St. Louis, Missouri (formerly of the Monsanto Company) and Dr. Ryoji Noyori of Nagoya University, Chikusa, Nagoya, Japan. After more than a decade of trying, in 1980 Dr. Sharpless figured out how to force a chemical reaction to go one-handed. The winning combination turned out to be a mixture of two inexpensive commercial chemicals: a relatively simple titanium compound and either the right or left hand of a chemical called "tartrate."

The planting of 23 sets of three acorns one valley oak and two coast live oaks to a set capped off the initial phase of the plan to restore 5 acres disturbed by the installation of a storm water drain this summer, said SEAN ANDERSON , a postdoctoral fellow at the Center for Conservation Biology. Anderson helped round up the stars of a natural history exhibit, including a night snake, tree frogs, and blue-bellied and alligator lizards. "I touched a millipede," said a surprised-sounding DEBRA ZUMWALT , the university's general counsel, who came out for the morning with her 11-year-old daughter. Afterward, the exhibit slithered and scuttled back into the hills. WHEN NEWLY MINTED NOBEL LAUREATE K. BARRY SHARPLESS lectures in Braun Auditorium at the Mudd Chemistry Building Thursday afternoon, he'll be just a couple of flights of stairs away from where he made the breakthrough that led to his being awarded the Nobel Prize in chemistry Oct. 10. Sharpless, now at the Scripps Research Institute in La Jolla, was a Stanford chemistry professor in 1980 and working in a third-floor lab at Mudd when he developed a way to catalyze an oxidation reaction so that only one side of a molecule's mirror image is produced. The discovery is used in the synthesis of pharmaceuticals such as antibiotics, anti-inflammatory drugs and heart medicines.

Extractions: MANY naturally occurring molecules, particularly biological molecules, are found in two forms that are mirror images of each other, just as human hands mirror each other. Such molecules are chiral or handed, derived from the Greek word cheir, meaning hand. The two forms are called enantiomers. The amino acid alanine, for example, occurs as S-alanine and R-alanine. When the molecule is produced in the laboratory under normal conditions, a mixture containing equal amounts of the two enantiomers is obtained. That is, the synthesis is symmetrical. Asymmetric synthesis concerns the production of one of the enantiomers in excess over the other. In many applications, particularly pharmaceuticals, asymmetric synthesis is very important because, while one form may be beneficial to health, the other may even be harmful, as in the case of thalidomide. One form of this drug was known to prevent nausea in pregnant women while the other was found to cause foetal damage. For many biological molecules, nature seems to prefer one form over the other. In plant and animal systems amino acids, peptides, enzymes and other proteins, nucleic acids such as DNA and RNA and carbohydrates occur as only one kind of enantiomer. Receptors in human cells too are chiral and so they, like the glove to a hand, prefer to bind only to one form. In fact, the two enantiomers can have different effects on the cells. Limonene, for example, is chiral and occurs as S-limonene and R-limonene which produce quite different sensations in our olfactory cells. The former smells of lemons and the latter of oranges. Therefore, it becomes important to be able to produce the two enantiomers in pure and unmixed form. This is particularly important in the case of drugs, the active ingredients in many of which are chiral molecules.
