Title: Selective Functionalization of Pyridines, Diazine and Pharmaceuticals via Heterocyclic Phosphonium Salts
Abstract: Selective methods that can functionalize electron-deficient heterocycles are in great demand due to their prevalence in biologically active compounds. Pyridines and diazines, in particular, are widespread components of pharmaceutical compounds yet methods to transform these motifs into valuable derivatives are still greatly sought after. We will present a selection of catalytic and non-catalytic methods using  phosphorus intermediates that enable multiple new bond-constructions on these heterocycles. A particular emphasis will be placed on phosphorus ligand-coupling reactions that represent an alternative means to form C–C and C-Heteroatom bonds.

C-H and C-O functionalization via radical chaperones

 


Our research is focused on harnessing the untapped reactivity of abundant chemical feedstocks to enable late-stage functionalization of medicinally relevant molecules. We have recently developed new approaches for selective C-H and C-O functionalization of alcohols, amines, and carbonyls, using a combination of radical (1e-) and closed shell (2e-) processes that act in concert with one another. These radical chaperone strategies have enabled discovery of new classes of reactivity to streamline the synthesis of complex molecules with biological and industrial significance.

Title: Chemical Synthesis with Diaryliodonium Salts

Abstract: Aromatic rings are ubiquitous in molecules used in health, agriculture, technology, and energy fields.  Over the past decade, diaryliodonium salts have emerged as novel aryl-transfer reagents in both metal-catalyzed and metal-free reactions.  Our research is focused on using unsymmetrical aryl(auxiliary)iodonium salts in metal-free reactions and addressing key questions of chemoselectivity in aryl transfer.  Two competing pathways will be discussed: extrusion of arynes and direct ipso-substitution.  These pathways are exploited in the development of methods that access new chemical space and expand beyond the limitations of classic SNAr.

Bio: Dave obtained his BSc (Honors) from the University of Victoria (Victoria, BC, Canada) in 2005 and his PhD at the University of Ottawa (Ottawa, ON, Canada) in 2010 under the guidance of Prof. Keith Fagnou.  After an NSERC-funded postdoc with Eric Jacobsen (Harvard), Dave began his independent career at Portland State University in 2012.  He was promoted to Associate Professor with tenure in 2018.
