Research areas: Our research focuses on synthetic organic methodology, with an emphasis general synthetic transformations and catalysis by small molecules and in microenvironments. Our goal is to develop methods general enough to be applied to library synthesis, ultimately providing new tools for synthetic and medicinal chemists.

Beyond publications and presentations, the major product of the program has been its graduates. Group alumni generally proceed to graduate work in chemistry, medical and dental schools, or directly to careers in chemistry, where most have found employment in the petrochemical, fine chemical, and pharmaceutical industries.

A major focus of our recent research is the library synthesis of species containing γ-dicarbonyl derived fragments. Such fragments are structurally important in several families of pharmacologically active compounds. These include hydroxamic acid and γ-diamide species for use as matrix metalloproteinases inhibitors, and 4,5-dihydro-pyridazin-3-ones for use as cyclic nucleotide phosphodiesterase inhibitors.

We have chosen to utilize Meyers' bicyclic lactams as the primary scaffold for our synthesis as they allow us access to γ-dicarbonyls with controlled chirality. Meyers' bicyclic lactams have received considerable attention owing to their suitability in generating a number of heterocyclic systems containing chiral sites by alkylation of the lactam ring.

Their use as precursors to γ-dicarbonyl systems, however, has been limited by the relatively harsh conditions needed to cleave or hydrolyze the lactam. One of our recent successful efforts has been the development of a mild cleavage of bicyclic lactam species. We are developing generalized methods to convert the bicyclic lactam to the hydroxamic acids and 4,5-dihydropyridazin-3-ones.
