A representative example in the area of enantioselective organocascade catalysis is our laboratoryвЂ™s amine-catalyzed DielsвЂ“Alder/beta-elimination/conjugate addition cascade. Beginning from simple, achiral starting materials, an enantiopure organocatalyst or transition metal complex mediates a multi-step cascade sequence that generates both structural and stereochemical complexity in a single synthetic operation. As a general strategy, cascade catalysis mimics natureвЂ™s approach to molecular construction. In the field of total synthesis, our group draws inspiration from natureвЂ™s ability to rapidly construct enantiopure complex molecules through catalytic cascade reactions within enzyme active sites. As exemplified by this transformation, interfacing multiple modes of catalysis provides access to novel reactivity and challenging bond disconnections that cannot be accomplished by either catalyst in isolation. Most recently, in a collaborative effort with the Doyle group, we reported the productive merger of nickel and photoredox catalysis to enable the activation of usually вЂњbenignвЂќ functionality (carboxylic acids) in a decarboxylative cross-coupling with aryl halides. Through these efforts, we have discovered a number of powerful methodologies by combining organocatalysis with photoredox catalysis or more traditional transition-metal catalysis. Exploring combinations of multiple catalysts in a single flask, with two or more catalytic cycles working in concert, has become a key area of research in our laboratory. The unique reactivity of these complexes has attracted significant attention, in part due to their ability to functionalize non-traditional sites of reactivity.В Photoredox catalysis is now a burgeoning area of research across the synthetic community.Д®ach of the aforementioned areas of catalysis has proven to be a powerful strategy in its own right, and their implementation has led to the discovery of myriad individual reactions. Additionally, over the past several years, we have become interested in the application of photoredox catalysis to organic synthesis, wherein a transition-metal complex may be triggered by low-energy, visible light to perform single-electron transfers without requiring harsh conditions or stoichiometric oxidants or reductants. These robust amine catalysts are capable of generating diverse activated intermediates such as enamines, iminium ions and 3p-electron (SOMO) species, each of which may be coupled with numerous differentВ classes of reaction partners. In particular, our group has made contributions to the field of organocatalysis through the development and wide application of chiral imidazolidinone catalysts. Toward the goal of developing broadly useful strategies for organic synthesis, our research program is focused on platforms for reaction development involving organocatalysis, photoredox catalysis and metal-mediated catalysis. We place particular emphasis on the synthesis of moieties prevalent in medicinal agents, agrochemicalsВ and natural products, with the goal of streamlining existing synthetic routes and facilitating the discovery of new bioactive scaffolds. In this endeavor, we target the development of general strategies that can be implemented in a wide spectrum of chemical processes. We are inspired by the pursuit of new concepts in synthetic organic chemistry that allow access to structural and stereochemical motifs not readily available using conventional methods.
