Research from Emory’s Emerson Center for Scientific Computing has been highlighted by Chemical and Engineering News. The research, the result of a collaboration between the Emerson Center’s Djamaladdin D. Musaev and the Kenichiro Itami at Nagoya University in Japan, involves Cu-catalyzed C-H imidination. The article, “Onward to simpler C–H functionalizations” appears in the November 07-08 issue of Chemical & Engineering News both in print and online.

Photo Gallery: Emerson Symposium Brings Arieh Warshel to Emory

The 2016 Emerson Center Lectureship Award Symposium was held in Harland Cinema on September 23rd, 2016. Professor Arieh Warshel of the University of Southern California, the 2013 recipient of the Nobel Prize in Chemistry, was the Emerson award winner and keynote speaker. His talk was titled “How to Model the Action of Complex Biological Systems on a Molecular Level.” The symposium also featured talks by David Lynn, Brian Dyer, and R. Prabhakar (University of Miami). The symposium was hosted by Jamal Musaev and the Emerson Center for Scientific Computation. Financial support for the symposium came from the Emory’s Hightower fund, the Department of Chemistry, and Microway Technologies.

Emory Chemists Find “Huge Shortcut” for Organic Synthesis Using C-H Bonds

Graduate student Kungbiao Liao (Davies Group) is the first author of a new paper in Nature that describes a “huge shortcut” for organic synthesis of carbon-hydrogen (C-H) bonds of an alkane without using a connecting group. Solymar Negretti (Davies Group), Jamal Musaev (Emerson Center), John Bacsa (X-ray Center), and Huw Davies are additional authors.

From Emory’s eScienceCommons:

The streamlined process described in the paper holds tremendous potential for the synthesis of fine chemicals, such as those needed for the development of pharmaceuticals.

“Organic synthesis is all about simplicity,” [Huw Davies] says. “It may lead to a sophisticated outcome, but it has to be simple to carry out in order to have practical applications.”

The work in this paper was made possible in part by Emory’s NSF Center for Selective C-H Functionalization, led by Dr. Davies.

Collaborative study in Nature Communications Explores Recent Advances by Emory Scientists and International Colleagues

A recent study published in Nature Communications stems from an international collaboration between scientists in Emory’s own NSF Center for Selective C-H Functionalization and the Institute of Transformative Bio-Molecules (ITbM) at Nayoga University, Japan. The article “Decarbonylative organoboron cross-coupling of esters by nickel catalysis” details work that expands the scope of a Nobel Prize-winning carbon-carbon bond reaction. The expanded reaction uses aromatic esters and boronic acids as coupling partners in the presence of a nickel catalyst. The nickel catalyst is economically and environmentally friendly, making it strategically useful for pharmaceutical, agro-chemical, and organic materials applications.

The new research builds on the 2010 Nobel prize-winning Suzuki-Miyaura cross-coupling reaction, an extremely powerful strategy to synthesize a variety of significant organic compounds on an industrial scale. The reaction is usually catalyzed by a pallidium catalyst to couple boronic acids with organic hallides. The result is extremely powerful but its reaction partners can generate corrosive waste byproducts.

Researchers at ITbM and CCHF have demonstrated that readily available esters–carbonyl compounds found in fat and oils–can be used as alternative coupling partners, generating useful products such as derivatives of plant metabolites and a drug for treating hypertension, telmisartan.

Esters are known for their distinctive odors, such as banana and pineapple, thus making them a popular ingredient in perfumes. Due to their high commercial and synthetic accessibility, the use of esters to couple with boronic acids greatly expands the scope of available substrates for the Suzuki-Miyaura cross-coupling reaction.

Theoretical calculations conducted by Professor Djamaladdin Musaev, Director of the Emerson Center at Emory University, contributed valuable insight to the mechanism of the decarbonylative cross-coupling reaction between aromatic esters and boronic acids.

“This is a beautiful work in the frontier of organic transformations,” said Musaev. “I am grateful to Professor Itami and the entire ITbM team for providing the opportunity for us to contribute to this novel research project.”

In turn, Professor Ken Itami of ITbM praises Musaev for elucidating the unusual decarbonylative cross-coupling reaction. “This is obviously a result of the strong collaboration between ITbM and CCHF. We will continue to work together to conduct further optimization of the reaction system to expand its scope.”

Itami and his colleagues envisage that ongoing advances in this reaction method may lead to the development of new industrial processes for making biologically and structurally active compounds, including aliphatic esters.

Emory Report Profiles Emerson Center’s Musaev

Jamal Musaev is featured in an Emory Report profile, “‘Land of Fire’ ignites love of science.”

Jamal Musaev, director of Emory’s Cherry L. Emerson Center for Scientific Computation, is a native of Azerbaijan.

He grew up in the small, mountain town of Ordubad, during the heyday of the space race between the U.S. and the U.S.S.R.

“I loved physics, and from the time I was in sixth grade, I wanted to be an astronaut. That was my dream,” Musaev recalls.
