Samuel Danishefsky

The Danishefsky diene, developed by Samuel Danishefsky, is trans-1-methoxy-3-trimethylsilyloxy-1,3-butadiene, a highly reactive diene used in Diels-Alder reactions. It has become one of the most widely used reagents in synthetic organic chemistry for constructing six-membered ring systems with defined oxygen substitution.

Samuel Danishefsky holds positions at both Columbia University and Memorial Sloan Kettering Cancer Center in New York. His dual appointment reflects his career focus on synthesizing complex anticancer natural products with potential therapeutic applications.

Danishefsky has completed total syntheses of numerous complex anticancer natural products, including taxol (paclitaxel), the epothilones, and calicheamicin. His work at Memorial Sloan Kettering has been specifically motivated by developing new approaches to cancer chemotherapy through synthetic chemistry.

At Memorial Sloan Kettering Cancer Center, Danishefsky has served as chair of the Laboratory for Bioorganic Chemistry. His research there has focused on translating complex natural product synthesis into potential cancer therapies, including work on carbohydrate-based anticancer vaccines.
