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. Regarded by many as one of the greatest living chemists, he has developed numerous synthetic reagents, methodologies and total syntheses and has advanced the science of organic synthesis considerably.
An enamine is an unsaturated compound derived by the condensation of an aldehyde or ketone with a secondary amine. Enamines are versatile intermediates.
The Corey–Itsuno reduction, also known as the Corey–Bakshi–Shibata (CBS) reduction, is a chemical reaction in which an achiral ketone is enantioselectively reduced to produce the corresponding chiral, non-racemic alcohol. The oxazaborolidine reagent which mediates the enantioselective reduction of ketones was previously developed by the laboratory of Itsuno and thus this transformation may more properly be called the Itsuno-Corey oxazaborolidine reduction.
The Carroll rearrangement is a rearrangement reaction in organic chemistry and involves the transformation of a β-keto allyl ester into a α-allyl-β-ketocarboxylic acid. This organic reaction is accompanied by decarboxylation and the final product is a γ,δ-allylketone. The Carroll rearrangement is an adaptation of the Claisen rearrangement and effectively a decarboxylative allylation.
A chiral auxiliary is a stereogenic group or unit that is temporarily incorporated into an organic compound in order to control the stereochemical outcome of the synthesis. The chirality present in the auxiliary can bias the stereoselectivity of one or more subsequent reactions. The auxiliary can then be typically recovered for future use.
Sir David William Cross MacMillan is a Scottish chemist and the James S. McDonnell Distinguished University Professor of Chemistry at Princeton University, where he was also the chair of the Department of Chemistry from 2010 to 2015. He shared the 2021 Nobel Prize in Chemistry with Benjamin List "for the development of asymmetric organocatalysis".
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.
Horsfiline is an oxindole alkaloid found in the plant Horsfieldia superba, which is used in traditional herbal medicine. It has analgesic effects and has been the subject of research both to produce it synthetically by convenient routes and to develop analogues and derivatives which may have improved analgesic effects.
The Tsuji–Trost reaction is a palladium-catalysed substitution reaction involving a substrate that contains a leaving group in an allylic position. The palladium catalyst first coordinates with the allyl group and then undergoes oxidative addition, forming the π-allyl complex. This allyl complex can then be attacked by a nucleophile, resulting in the substituted product.
Phosphinooxazolines are a class of chiral ligands used in asymmetric catalysis. Their complexes are particularly effective at generating single enatiomers in reactions involving highly symmetric transition states, such as allylic substitutions, which are typically difficult to perform stereoselectively. The ligands are bidentate and have been shown to be hemilabile with the softer P‑donor being more firmly bound than the harder N‑donor.
Gregory (Greg) C. Fu is a Professor of organic chemistry at the California Institute of Technology and the Norman Chandler Professor of Chemistry. The current research interests of the Fu laboratory include metal-catalyzed coupling reactions and the design of chiral catalysts. In particular, the group is focused on the development of nickel-catalyzed enantioselective cross-couplings of alkyl electrophiles and on photoinduced, copper-catalyzed carbon–heteroatom bond-forming reactions. The group works in collaboration with the laboratory of Professor Jonas C. Peters.
Abigail Gutmann Doyle is a Professor of Chemistry at the University of California, Los Angeles, where she holds the Saul Winstein Chair in Organic Chemistry. Her research focuses on the development of new chemical transformations in organic chemistry.
Sarah Elizabeth Reisman is a Chemistry Professor at the California Institute of Technology. She received the (2013) Arthur C. Cope Scholar Award and the (2014) Tetrahedron Young Investigator Award for Organic Synthesis. Her research focuses on the total synthesis of complex natural products.
Michael J. Krische is an American chemist and Robert A. Welch Chair in Science at the Department of Chemistry, University of Texas at Austin. Krische has pioneered a broad, new family of catalytic C-C bond formations that occur through the addition or redistribution of hydrogen. These processes merge the characteristics of catalytic hydrogenation and carbonyl addition, contributing to a departure from the use of stoichiometric organometallic reagents in chemical synthesis.
F. Dean Toste is the Gerald E. K. Branch Distinguished Professor of Chemistry at the University of California, Berkeley and Faculty Scientist at the Chemical Sciences Division of Lawrence Berkeley National Lab. He is a prominent figure in the field of organic chemistry and is best known for his contributions to gold chemistry and asymmetric ion-pairing catalysis. Toste was elected a member of the National Academy of Sciences in 2020, and a member of the American Academy of Arts and Sciences in 2018.
Richmond Sarpong is a Ghanaian-American chemist who is a professor at the University of California, Berkeley. Sarpong works on natural product total synthesis to better understand biological systems and allow for the development of novel therapeutics. He was awarded a Guggenheim Fellowship in 2017, and was elected a fellow of the American Association for the Advancement of Science in 2020. He serves on the editorial boards of Organic Syntheses, Accounts of Chemical Research and Synlett.
Teruaki Mukaiyama was a Japanese organic chemist. One of the most prolific chemists of the 20th century in the field of organic synthesis, Mukaiyama helped establish the field of organic chemistry in Japan after World War II.
Jin-Quan Yu is a Chinese-born American chemist. He is the Frank and Bertha Hupp Professor of Chemistry at Scripps Research, where he also holds the Bristol Myers Squibb Endowed Chair in Chemistry. He is a 2016 recipient of the MacArthur Fellowship, and is a member of the American Academy of Arts and Sciences, American Association for the Advancement of Science, and the Royal Society of Chemistry. Yu is a leader in the development of C–H bond activation reactions in organic chemistry, and has reported many C–H activation reactions that could be applicable towards the synthesis of drug molecules and other biologically active compounds. He also co-founded Vividion Therapeutics in 2016 with fellow Scripps chemists Benjamin Cravatt and Phil Baran, and is a member of the scientific advisory board of Chemveda Life Sciences.
