University of Michigan

Welcome to the Stephenson Group at the University of Michigan. Our group is interested in developing methodologies that harness the power of visible light to mediate reactions that are useful for the synthesis of biologically active molecules. We conduct photochemical reactions in both batch and continuous flow manifolds with the goal of developing methods to access unique chemical space.




Alex defends her Dissertation!

Taylor and Logan's insightful perspective on current art and future directions in isosteric replacement of anilines is out now in ACS Med. Chem. Lett.

November 8, 2019

Our second generation approach to the preparation of 1-aminonorbornanes using direct imine excitation was published in Angew. Chem. Great work everyone!

Join us at the 9th Pacific Symposium on Radical Chemistry

February 5, 2019

Prof. Stephenson is honored to be hosting the 9th Pacific Symposium on Radical Chemistry (PSRC-9) at the Asilomar Conference Grounds in Pacific Grove, California, USA, from June 16th to 21st, 2019. For more information about this meeting check out the conference website or follow on Twitter. We hope to see you there!


November 26, 2018

Our collaboration with the Pratt group (U. Ottawa) has yielded another publication - this time combining a new approach for the synthesis of persistent radicals with their investigation as antioxidants. Great work everyone!

November 21, 2018

We are excited to share that our group has been awarded an NIH R01 grant to investigate the use of 1-aminonorbornanes as aniline bioisosteres for drug discovery. The initial investigation of this idea was recently published in Chem! We look forward to pushing this work forward with great collaborators in the Duncan, Jackson, Mapp, Pollastri, Chilvers, and Sundin labs!

September 27, 2018

Our continued investigation into the radical Smiles rearrangement has yielded a method in which simple arylsulfonylacetamides can be used for alkene aminoarylation to access biologically relevant scaffolds. Great work everyone!

August 13, 2018

Our tutorial review has been published in Chemical Society Reviews as part of a themed issue on "New Enabling Strategies for Natural Product Synthesis". Great work by everyone involved!

July 19, 2018

Our collaboration with Eli Lilly has yielded another paper involving aryl migration to access important pharmaceutical scaffolds. Congratulations everyone!

Summer Students Begin Research

June 8, 2018

Three students have joined the group for summer research. Anthony (Oberlin '18) starts his graduate studies, while Ethan (Michigan '19) and Annika (Indiana '20) seek to supplement their undergraduate work. Welcome all!

Back to back publications in Organic Letters

June 1, 2018

Our efforts investigating the use of heteroaryl N-oxides as redox auxiliaries for heteroarene functionalization have culminated in back to back publications in Organic Letters. Congrats to everyone involved!
