The primary field of study in my group at UT Arlington is chemical synthesis and catalysis. We target to develop direct, more efficient, streamlined synthetic methods to synthesize transformative molecules with significant functions. In order to achieve the goal, our strategy is to rationally design transition-metal/ligand catalyst complexes, to understand the function of the catalysts, and to utilize them for developing catalytic reaction methods. Specific areas of interest include transition metal-catalyzed hydrofunctionalization and dehydrogenative functionalization of unsaturated C–C bonds, catalytic C–H and C– C bond functionalization, and direct cross-coupling reactions.

Jeon research overview

We are also engaged in synthesis of chemically and biologically significant molecules including natural and unnatural molecules. The target-oriented synthetic study not only provides planned synthetic target molecules, but also often reveals new, unprecedented interesting reactivity and selectivity. We hope to apply the lessons from discovery of new reaction methods and synthesis of bioactive molecules into therapeutic areas.

Finally, we are currently engaged in to provide a new approach to design, fabricate, and characterize new nano-materials for energy-related fields.

Junha Jeon joined the University of Texas at Arlington in fall of 2011. He completed a Bachelor’s and Master’s degrees in chemistry at the Sungkyunkwan University in Korea in the laboratory of Professor Chan-Mo Yu, where he studied catalytic asymmetric allylic transfer reactions for the enantioselective synthesis of dienyl and enynyl alcohols. His doctoral research was then conducted under the guidance of Professor Thomas R. Hoye at the University of Minnesota. Within the Hoye group, he focused on natural product synthesis and method development (Sequential Ring-Closing/Cross Metathesis strategy and Relay Ring-Closing Metathesis, RRCM). The doctoral thesis title was “New Applications and Strategies in Olefin Metathesis: A Total Synthesis of (+)-Gigantecin and a Total Synthesis of (+)-Peloruside A”. After completing his doctoral work, he joined the laboratory of Professor Amos B. Smith, III at the University of Pennsylvania as a Postdoctoral Fellow, where he continued to work on the natural product synthesis (nodulisporic acid A) utilizing metal mediated cyclization strategy. Additionally, he involved Asymmetric Anion Relay Chemistry (AARC) and rapid library synthesis of natural product-like compounds utilizing anion relay chemistry
The Jeon laboratory at UT Arlington is working on the development of highly innovative and efficient synthetic methods and their functional applications.
