Samuel J. Danishefsky (born March 10, 1936) is an American chemist working as a professor at both Columbia University and the Memorial Sloan-Kettering Cancer Center in New York City. [2]
Samuel J. Danishefsky was born in 1936 in the United States. He completed his B.S. from Yeshiva University in 1956. He earned his Ph.D. in chemistry from Harvard University in 1962 with Peter Yates, which partially overlapped with a National Institutes of Health postdoctoral fellowship in the laboratory of Gilbert Stork at Columbia University. [3]
After completing his PhD, he became professor at the University of Pittsburgh, where he eventually attained the rank of University Professor and taught until 1979. From 1979 to 1993, he was a professor at Yale University, where he rose to the rank of Sterling Professor of Chemistry. By 1991 he was sharing his time with Memorial Sloan-Kettering Cancer Center as director of the Laboratory for Cancer Research Bioorganic Chemistry, becoming chair in 1993. He accepted an appointment as professor at Columbia University in 1993, and now splits his time between Columbia and Sloan-Kettering.
Samuel J. Danishefsky is known for his role in synthesizing the many complex organic compounds, many of which are related to pharmaceuticals. Among the molecules synthesized by Danishefsky at Columbia University are epothilones and calicheamicin, which are natural products with promise as anti-cancer agents.
The Danishefsky Taxol total synthesis was the third synthesis of taxol, a highly topical natural product. [4] Together with the Holton Taxol total synthesis and the Nicolaou Taxol total synthesis, these multistep sequences illustrate the state of the art in total synthesis.
In 1995/96 he shared the Wolf Prize in Chemistry with Gilbert Stork of Columbia University for "designing and developing novel chemical reactions which have opened new avenues to the synthesis of complex molecules, particularly polysaccharides and many other biologically and medicinally important compounds". [5]
He is the recipient of several other awards including the American Chemical Society's Guenther Award and Aldrich Award for Creative Work in Synthetic Organic Chemistry, the F.A. Cotton Medal for Excellence in Chemical Research of the American Chemical Society, the Tetrahedron Prize (1996), the Arthur C. Cope Award (1998), the New York City Mayor's Award for Science and Technology, and the Bristol Myers Squibb Lifetime Achievement Award. In 2006, he was awarded the Benjamin Franklin Medal in Chemistry for his achievements in synthetic organic chemistry, particularly for the development of methods for preparing complex substances found in nature, and their emerging applications in the field of cancer treatment. [6] He is a member of the Board of Scientific Governors at The Scripps Research Institute. He holds an honorary doctorate from Yeshiva University.
Elias James Corey is an American organic chemist. In 1990, he won the Nobel Prize in Chemistry "for his development of the theory and methodology of organic synthesis", specifically retrosynthetic analysis.
Organic synthesis is a branch of chemical synthesis concerned with the construction of organic compounds. Organic compounds are molecules consisting of combinations of covalently-linked hydrogen, carbon, oxygen, and nitrogen atoms. Within the general subject of organic synthesis, there are many different types of synthetic routes that can be completed including total synthesis, stereoselective synthesis, automated synthesis, and many more. Additionally, in understanding organic synthesis it is necessary to be familiar with the methodology, techniques, and applications of the subject.
Kyriacos Costa Nicolaou is a Cypriot-American chemist known for his research in the area of natural products total synthesis. He is currently Harry C. and Olga K. Wiess Professor of Chemistry at Rice University, having previously held academic positions at The Scripps Research Institute/UC San Diego and the University of Pennsylvania.
The Danishefsky Taxol total synthesis in organic chemistry is an important third Taxol synthesis published by the group of Samuel Danishefsky in 1996 two years after the first two efforts described in the Holton Taxol total synthesis and the Nicolaou Taxol total synthesis. Combined they provide a good insight in the application of organic chemistry in total synthesis.
Paclitaxel total synthesis in organic chemistry is a major ongoing research effort in the total synthesis of paclitaxel (Taxol). This diterpenoid is an important drug in the treatment of cancer but, also expensive because the compound is harvested from a scarce resource, namely the Pacific yew. Not only is the synthetic reproduction of the compound itself of great commercial and scientific importance, but it also opens the way to paclitaxel derivatives not found in nature but with greater potential.
Gilbert Stork was an organic chemist. For a quarter of a century he was the Eugene Higgins Professor of Chemistry Emeritus at Columbia University. He is known for making significant contributions to the total synthesis of natural products, including a lifelong fascination with the synthesis of quinine. In so doing he also made a number of contributions to mechanistic understanding of reactions, and performed pioneering work on enamine chemistry, leading to development of the Stork enamine alkylation. It is believed he was responsible for the first planned stereocontrolled synthesis as well as the first natural product to be synthesised with high stereoselectivity.
Eric N. Jacobsen is the Sheldon Emery Professor of Chemistry and former chair of the department of chemistry and chemical biology at Harvard University. He is a prominent figure in the field of organic chemistry and is best known for the development of the Jacobsen epoxidation and other work in selective catalysis.
Larry E. Overman is Distinguished Professor of Chemistry at the University of California, Irvine. He was born in Chicago in 1943. Overman obtained a B.A. degree from Earlham College in 1965, and he completed his Ph.D. in chemistry from the University of Wisconsin–Madison in 1969, under Howard Whitlock Jr. Professor Overman is a member of the United States National Academy of Sciences and the American Academy of Arts and Sciences. He was the recipient of the Arthur C. Cope Award in 2003, and he was awarded the Tetrahedron Prize for Creativity in Organic Chemistry for 2008.
