Searching for Efficient Reactions in Complex Molecular Environments
Complex natural products have provided perennial inspiration for the development of synthetic methods, and enzymes have provided an analogous platform for the conception of new catalysts. This lecture will recount an interplay of experiments stimulated by these two major classes of naturally occurring substances. Specifically, the discovery and use of peptides as catalysts for a variety of asymmetric bond formations – on complex molecular scaffolds – will be presented. Likewise, applications of these catalysts to the selective modification of complex molecules, including biologically active natural products, will be described. The impact of these structural alterations on biological activity will be discussed in selected cases. In all cases, a consideration of the efficiency of the catalytic processes, and critically, catalyst identification, will be undertaken.
Professor Gary Molander
Novel Organoboron Reagents and Reactivities
Cross-coupling reactions employing boronic acids have revolutionized the pharma, agrochemical, and other industries by providing facile access to structural systems that were previously difficult to synthesize efficiently. Until recently, little effort has been expended toward further development of the most important component of the process – the organoboron reagent itself. Boronic acids, commonly used for Suzuki-Miyaura coupling, are far from ideal. Because of competitive protodeboronation, literature protocols for cross-coupling employ excess boronic acid to insure a complete conversion of the electrophilic component of the reaction.
Alternative routes to boronic acids and their derivatives utilizing various dibora species will be discussed, with an emphasis on the synthesis and use of the more robust organotrifluoroborate reagents. Novel syntheses of a variety of substructural synthons will be outlined, and unique reagents and chemical transformations will be unveiled as well.
Dr. Greg Hughes
Biocatalysis as an enabling tool for drug development
The use of enzymes as catalysts is becoming an increasingly important tactic in the production of pharmaceuticals. This presentation will give an overview of the applications of these tools to the development and production of medicines at Merck, with particular emphasis on the use of engineered enzymes. A brief review of the sitagliptin transaminase development efforts will be presented, with the majority of the presentation focusing on subsequent applications which were inspired and enabled by this work.
Professor Paul Chirik
Base Metal Catalysis for Organic Synthesis: Applications and Opportunities
Transition metal catalysis has revolutionized organic synthesis by enabling new transformations with unprecedented selectivity. Often times, these processes rely on precious metals such as ruthenium, rhodium, iridium and platinum. Our group has been exploring more abundant first row transition metals as alternatives in catalysis. Open questions include – “how can the electronic structure of base metals be altered to achieve the reactivity more traditionally associated with heavier transition metals?” and “can the unique electronic structures of base metals be exploited for new transformations?” Our group has utilized redox-active ligands – those that undergo reversible electron transfer with the transition metal to enable two-electron chemistry with reduced iron and cobalt compounds. This approach has produced catalysts with superior activity and selectivity in reactions such as olefin hydrosilylation and hydrogen than established precious metal compounds. More recently we have focused on the discovery of new base metal precursors for high throughput catalyst evaluation. New phosphine-ligated cobalt compounds have been discovered for asymmetric hydrogenation which demonstrate a new electronic structure paradigm in base metal catalysis. My lecture will focus on the application of base metal catalysis to important transformations and highlight the role of electronic structure on function and mechanism.
Professor Dalibor Sames
C-H Bond Functionalization in Complex Organic Chemistry
The possibility of direct and selective introduction of a new functionality or a new C-C bond via C-H bond functionalization has long intrigued organic chemists as it provides new strategic opportunities for the synthesis of complex organic compounds. I will provide an overview of the efforts in our laboratories aimed at development of new chemical reactions and strategic approaches in organic synthesis. Namely, I will discuss the design of catalytic transformations of both sp2 and sp3 C-H bonds (e.g., C-H arylation of saturated heterocycles and heteroarenes, electrophilic C-H/alkene/alkyne coupling triggered by hydride transfer, and hydroarylation of alkenes and alkynes). Recent advances in scope advancement and mechanistic understanding of the palladium-carboxylate catalytic system (for C-H arylation of arenes and heteroarenes), as well as a new catalytic system for C-H oxidation of pharmaceuticals and pharmaceutical-like compounds, will be discussed.
Professor Michael Krische
Formation of C-C Bonds via Hydrogenation and Transfer Hydrogenation
Carbon-carbon bond formation is central to the endeavor of chemical synthesis. The largest volume application of homogenous metal catalyzed C-C coupling is alkene hydroformylation - a “C-C bond forming hydrogenation”. Our laboratory is engaged in the first systematic efforts to develop C-C bond forming hydrogenations beyond hydroformylation - processes wherein two or more reactants are hydrogenated to form a single, more complex product.1 Using cationic rhodium and iridium catalysts, we have found that diverse π-unsaturated reactants reductively couple to carbonyl compounds and imines under hydrogenation conditions, offering a byproduct-free alternative to stoichiometric organometallics in a range of classical C=X (X = O, NR) addition processes. This concept is extended further via “C-C bond forming transfer hydrogenation”. In such processes, the exchange of hydrogen between alcohols and unsaturated reactants serves to generate aldehyde-organometal pairs that combine to give products of carbonyl addition or hydrohydroxyalkylation. Direct alcohol CH-functionalization in this manner is again byproduct-free, and avoids discrete redox manipulations often required to convert alcohols to aldehydes. Representative transformations are given below.2,3

Rutgers Catalysis and Sustainability
The Rutgers Catalysis Research Center (RCRC) supports initiatives by the Rutgers Institute for Materials, Devices, and Nanotechnology (IAMDN) and the Rutgers Energy Institute (REI) and many faculty members in multiple departments around Rutgers who have common research interests in catalysis research. The center consists of researchers from the Departments of Chemistry, Physics, Chemical Engineering, Materials Science, Biological Sciences, Biochemistry, the Laboratory for Surface Modification (LSM), REI, IAMDN, etc.
The Rutgers Catalysis Research Center’s mission is to develop novel homogeneous and heterogeneous catalysts, photocatalysts, biocatalysts, and nanocatalysts that enable greener and energy-efficient routes for the productions of various fine chemicals, pharmaceuticals, commodity chemicals, biofuels, plastics and synthetic materials. Researchers in the center also study fundamental surface science, theoretical aspects of catalysts and catalysis, and investigate catalyst structures and their structure-activity relationships. The center catalyzes mutual interactions and interdisciplinary collaborations among many researchers throughout the greater Rutgers community. Members of the RCRC also actively cooperate and form partnerships with local members of catalysis societies such as the ACS GCI Pharmaceutical Roundtable and the rich catalysis intensive chemical industries in and around New Jersey.
Rutgers University is a leader in sustainability. One example is the Rutgers University Seven Acre Solar Farm. This facility is one of the largest renewable energy systems on a single campus in the United States. The 1.4 megawatt solar farm generates approximately 11 percent of the electrical demand of the Livingston Campus, reduces the university's carbon dioxide emissions by more than 1,300 tons per year and saves Rutgers tens of thousands of dollars per year.
Rutgers University is also an award-winning, nationally recognized leader in recycling. Over 67% of our waste is diverted from landfills! Please look for recycling opportunities at the symposium.
