  • Research

  • The Cowen group's research program focuses on the development of new synthetic methods for the preparation of small, functional organic compounds. Special emphasis centers on the discovery of unique asymmetric reactions to enable the selective construction of complex chiral molecular architectures. The design of small-molecule catalysts and ligands for both non-metal and metal-mediated transformations are key research activities ongoing in the laboratory. Additionally, the investigation of detailed mechanistic reaction pathways is of paramount importance to the maturation of any new synthetic method. A particular goal of our efforts in chemical synthesis is to produce valuable end products for potential pharmaceutical or material-based applications.
