Physical organic and bioorganic chemistry


My research group is interested in the physical and bioorganic chemistry of synthetic and natural receptors and catalysts. Using a combination of synthesis, NMR, slow and fast kinetics, and computer modeling, we design and implement studies oriented at the development of compounds which perform certain functions and tasks. In specific, we focus upon catalysts of phosphoryl and glycosyl transfers, receptors for carbohydrates and enolates, and single and multi-analyte sensors. In addition, we seek to form polymeric molecules that exhibit unique abiotic secondary structure and are useful in novel combinatorial library applications.

In the arena of phosphoryl transfer, the work involves investigation of the cooperativity of guanidiniums, metals and general bases. These functional groups are common elements of natural phosphatases. We make simple synthetic analogs of the natural systems. For example, bis-guanidinium structures have been found to bind and enhance the imidazole catalyzed hydrolysis of RNA. We are currently incorporating general bases and electrophilic metals as a means of producing a multifunctional RNA cleaving artificial enzyme.

Finally, as a means of developing sensors, we are pursuing the formation of combinatorial libraries of non-peptidic structures and polyguanidiniums. The goal is the formation of libraries of these novel polymers, from which useful receptors can be isolated by various screening methods. This is a new area of research for our group, but in a similar manner to our other projects, it nicely combines synthetic and molecular biology approaches to achieving practical results.
