Key takeaways

  • Samuel J. Danishefsky belongs to chemistry; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Samuel J. Danishefsky to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Samuel J. Danishefsky from memory before moving on to harder problems.

Reference excerpt

Samuel Joseph 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.

Birth and education 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.

Academic career 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.

Research

Samuel J. Danishefsky is known for his role in synthesizing 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. 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.

Awards and honors 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". 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. He is a member of the Board of Scientific Governors at The Scripps Research Institute. He holds an honorary doctorate from Yeshiva University.

Worked examples

Example 1 — a first encounter with Samuel J. Danishefsky

Start with the simplest possible case. Write down what Samuel J. Danishefsky claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Samuel J. Danishefsky before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Samuel J. Danishefsky ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Samuel J. Danishefsky

In research
Samuel J. Danishefsky appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Samuel J. Danishefsky in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Samuel J. Danishefsky is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1936 births, 21st-century American chemists, American organic chemists, so understanding it makes those chapters shorter.
In everyday life
Look for Samuel J. Danishefsky outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
