Jesse Carrick, Tennessee Tech University, "Experiential Investigations in Organic Synthesis"

Research in the Carrick group is focused in three distinct, but complementary areas: 1) Design and synthesis of novel complexants for chemoselective minor actinide extraction, 2) Total synthesis of biologically relevant natural products, and 3) Development of efficient methods for the construction of functionalized synthons for use in the synthesis of complex molecules.

Project 1.  Synthetic approaches to chemoselective minor actinide extraction

Effective separation of the minor actinides from lanthanides resident within used nuclear fuel in an environmentally conscious manner continues to inspire significant research effort. Soft-Lewis basic ligands have shown promise for chemoselective separation of trivalent actinides from lanthanides enabling the opportunity for recycling or subsequent transmutative processes.  Studies in this laboratory have focused on streamlining synthetic access to a diverse array of N-donors. Synthetic work has revealed the ability to directly telescope intermediate hydrazonamides of pyridine-2-carbonitrile, pyridine-2,6-dicarbonitrile, [1,10]-phenanthroline-2,9-dicarbonitrile, and related congeners to the 1,2,4-triazineand bis-1,2,4-triazines, respectively, under mild conditions.  Recent results have also shown the ability to expedite access to compounds with amphiphilic potential through Pd-catalyzed diamination. The ultimate goal of our work in this area is to install the necessary functionality on a chemoselective complexant scaffold which:  negates the need for a solubility modifier, is soluble in a process relevant solvent, and prevents third-phase formation while possessing strong hydro- and radiolytic stability.  Current synthetic method development as well as preliminary separations data will be presented.


Project 2.  Efforts toward the asymmetric total synthesis of hamigeromycin b

Hamigeromycin B is an aromatic natural product with extensive acetogenic character isolated as a  secondary metabolite of the soil fungus H. avellanea found in Thailand in 2008.  This resorcylic acid lactone has an extensively functionalized polyketide subcomponent and possesses structural features similar to molecules that display anti-malarial activity, selective cytotoxicity, as well as inhibitory action of HSP-90. The successful completion of the aromatic synthon and substantive progress towards the functionalization of the pyranone ring will be described.

Sarah Brinkley, Various Vineyards Worldwide, "Traveling for Coffee and Wine: A Lesson on Food Production"

Coffee and wine production details are presented. Examples are given of how undergraduate lab work has much to do with injecting quality into both industries. Topics include: chemical techniques used for harvesting decisions, experiments in fruit processing, and the importance of compost.


Xuan Zhao, University of Memphis, "Electro- and photolytic production of hydrogen by cobalt complexes with pentadentate ligands"

The design of metal catalysts for the production of H2, a clean and renewable fuel, required understanding of the electronic and steric factors on catalytic properties such as overpotential and turnover frequency (TOF). The catalytic properties for H2 evolution by cobalt complexes with a pentadentate ligand, N,N-bis(2-pyridinylmethyl)-2,2'-bipyridine-6-methanamine (DPA-Bpy), and its derivatives with electron-donating groups, will be discussed.
