The BBVA Foundation Frontiers of Knowledge Award in Basic Sciences goes to Stephen Buchwald for creating more efficient, stable, broad-spectrum catalystsof importance in drug discovery

• Buchwald, a professor at MIT,was engaged in purely basic research, when the pharmaceutical industry awakened him to the potential of his work for obtainingcarbon-carbon and carbon-nitrogen bonds, a project he would see through to fruition
• The catalysts he constructed with palladium and copper are now being used to synthesize novel moleculesof interest indiseases like cancer, AIDS, rheumatoid arthritis or diabetes
• In the ten years from 1999 to 2009 he was the world’s most cited chemist per paper, with an h-index of 123

Madrid, January 20, 2015.-The BBVA Foundation Frontiers of Knowledge Award in Basic Sciences has gone in this seventh edition to U.S. chemist Stephen Buchwald “for the development of catalytic routes based on palladium and copper to construct carbon-nitrogen and carbon-carbon bonds,” an advance with “great impact” on the “efficient synthesis of modern pharmaceuticals and compounds for agricultural use,” in the words of the prize jury.

The chemistry enabled by the achievements of Stephen Buchwald, a professor at Massachusetts Institute of Technology (MIT), “is now being applied to the creation of drugs for numerous diseases including many forms of cancer, AIDS, rheumatoid arthritis, inflammation and diabetes,” the citation continues.

If a chemist’s work is largely about adding implements to a “toolbox” with which to constructnew compounds,then Buchwald’s addition would be the catalysts for formingcarbon-nitrogen and carbon-carbon bonds. These bonds, carbon-nitrogen particularly, are in wide use in the pharmaceutical industry, but before Buchwald’s contribution, it was extremely hard to obtain them systematically due to the instability and limitationsof the catalysts available.

Every chemical reaction requires a certain activation energy. What catalysts do is modify this activation energy by boosting or inhibiting it, which alters the reaction speed. The catalysts that Buchwald created in the first decade of the 21st century lower activation energy so the reaction happens much faster but also in a more stable, predictable way. They also span a broad spectrum of reactivity, making them highly effective instruments for the industrial production of molecules.

Organometallic catalysts consist of a ligand, formed by organic molecules, and a metal center, in Buchwald’s case palladium or copper. As jury secretary Avelino Cormaexplains, “what we now call the Buchwald ligandis electron-rich and air-stable, yielding a highly active organometallic catalyst with a wide spectrum of reactivity. Its stability, moreover,facilitates production at an industrial scale.”

Stephen Buchwald (1955, Indiana, United States) declared himself “very excited” yesterday on receiving the news at his desk at MIT. Chemistry, he relates, was “a challenge” that he “fell in love with”thanks to the enthusiasm of a high school teacher. It is a science in which he sees “fundamental but also practical aspects, because if youget some success, your results can find applications in widely different areas.”

Success has not eluded him, and he admits that it is vastly encouraging to see the products, pharmaceuticals especially, that have been manufactured thanks to his research: “It is thrilling to know that someone has used my work to make a drug that will help many people.”

At the same time he acknowledges that what attracted him to research was the fundamental rather than the applied side. Buchwald completed a degree in chemistry at Brown University then went on to earn a PhD from Harvard in 1982. His thesis work, with Jeremy R. Knowles, concerned the mechanism of phosphoryl transfer reactions in chemistry and biochemistry. And his postdoctoral research at the California Institute of Technology (Caltech) was also of a basic nature.

In 1984, he joined the faculty at MIT, where he rose to a professorship in 1993. It was in this last year that he initiated a line of work with a more applied focus, exploring the formation of carbon-nitrogen bonds. Gradually this new research took up more and more of the lab’s time, eventually becoming what is so far the crowning achievementin Buchwald’s career, though he still likes to maintain “a balance” in his group between more fundamental and applied work.

The source of the change was the interest shown by the pharmaceutical industry in one of his basic outcomes: “They explained to me how pressing the need was [to be able to form carbon-nitrogen bonds], so we understood this was something important, and put a growing effort into the project.”

In thiscompetitive field, he credits the members of his group with contributing to a house method where each idea is experimentally tested and modified in consequence until arriving at the “optimal system”.

The ligand in the catalyst for the carbon-nitrogen bond was some seven years in development, and that of the carbon-carbon bond a little less. For Buchwald, though, the challenge is still not over. His latest work is focusedon carbon-fluorine and carbon-trifluoromethyl bonds, “further expanding the possibilities for making new molecules,” the citation concludes.

Buchwald is the co-author of over 420 papers in international journals and 44 issued patents. In 1999-2009 he was the chemist with thehighest number of citations per paper, attaining an h-index of 123.

A member of the American Academy of Arts and Sciences and the U.S. National Academy of Science, his career accomplishments have been further recognized by the Award for Creative Work in Synthetic Organic Chemistryand Award in Organometallic Chemistry of the American Chemical Society (ACS), the Linus Pauling Medal and the MERIT award of the National Institutes of Health.

About the BBVA Foundation Frontiers of Knowledge Awards

The BBVA Foundation promotes, funds and disseminates world-class scientific research and artistic creation, in the conviction that science, culture and knowledge in its broadest sense hold the key to a better future for people. The Foundation designs and implements its programs in partnership with leading scientific and cultural organizations in Spain and abroad, striving to identify and prioritize those projects with the power to move forward the frontiers of the known world.

The BBVA Foundation established its Frontiers of Knowledge Awards in 2008 to recognize the authors of outstanding contributions and radical advances in a broad range of scientific, technological and artistic areas congruent with the knowledge map of the late 20th and 21st centuries, and others that address central challenges, such as climate change and development cooperation, deserving of greater social visibility and recognition.

Their eight categories include classical areas like Basic Sciences (Physics, Chemistry and Mathematics) and Biomedicine, and other, more recent areas characteristic of our time, ranging from Information and Communication Technologies, Ecology and Conservation Biology, Climate Change and Economics, Finance and Management to Development Cooperation and the innovative realm of artistic creation that is Contemporary Music.

The juries in each category are made up of leading international experts in their respective fields, who arrive at their decisions in a wholly independent manner, applying internationally recognized metrics of excellence. The BBVA Foundation is aided in the organization of the awards by the Spanish National Research Council (CSIC), the country’s premier multidisciplinary research body. As well as designating each jury chair, the CSIC is responsible for appointing the Technical Evaluation Committees that undertake an initial assessment of candidates and draw up a reasoned shortlist for the consideration of the juries.

Committee members in the Basic Sciences category wereJuan Manuel García Ruiz,CSIC Research Professor at the University of Granada; Laura Lechuga Gómez, Research Professor in the Center for Research on Nanoscience and Nanotechnology (CSIC); Rosa Menéndez López, Research Professor in the National Carbon Institute (CSIC); and Francisco Javier Rojo Marcos, Senior Scientific Researcher in the Institute for Chemical Research (CSIC-University of Sevilla).
