Brønsted Acid Catalyzed Chromophore Activation

Evan, Matt, and Bohyun investigated a novel strategy for highly enantioselective organocatalytic photochemistry in which no individual reaction component absorbs light. Very pleased to announce the publication of this collaborative project with the Baik group in Nature Comms.

Asymmetric γ-alkyoxycarbonyl synthesis

Xiao and Yukki’s study of asymmetric Giese additions involving α-silylethers involves an in-depth mechanistic analysis of holistic photocatalyst considerations for successful photocatalytic reactions. Check out the paper in OL!

Oxidative Alkene Functionalizations

Nic and Grace have developed a protocol for intramolecular oxidative functionalization of sterically bulky alkenes with diverse heteronucleophiles as a way to show that photoredox catalysis can address long-standing limitations of transition metal catalyzed processes. See the ASAP in JACS!

Cyclobutaneboronate ester building blocks

Congratulations to Spencer, Jesse, Luca, Rowan, and Niecia! Their paper on the photosensitized synthesis of complex cyclobutane boronate esters is now online at Org Lett.

Congratulations Meredith!

Congratulations to Yoon lab first year Meredith Hughes for winning a GRFP honorable mention in a fiercely competitive year!

Photochemical Oxidase Review

Nic thought a lot about how to design photochemical oxidation reactions during his PhD, and his analysis is part of this great tutorial review in Chem Soc Rev.

A New Kochi-Solomon Catalyst

Chris and Luis discovered a new catalyst system that improves the scope of the Kochi-Salomon reaction. Now online at ACIE!

Divergent Photoreactions of Ketones

Jian and Xiao’s study of the divergent reactions of benzoylformates is online at Org Lett! This paper shows how the rational choice of reaction conditions can partition a photocatalytic reaction between photoredox and triplet sensitization manifolds and thus result in completely different products from the same reactants. It was a privilege to publish back-to-back with …

Diversity and Inclusion in Organic Chemistry

Tehshik co-authored an Editorial with Sarah Reisman, Richmond Sarpong, and Matt Sigman that has been jointly published by JOC, OL, Organometallics, and ACS Central Science as a rebuttal to the recent Hudlicky Perspective article. We felt it was important, as members of Hudlicky’s scholarly community, to articulate an evidence-based case for why his essay’s views …

LED-NMR Monitoring of Fast Photocatalytic Reactions

Kaz and Wes’ work on the use of the LED-NMR setup in our NMR facility is online at ChemPhotoChem.  A fun collaboration with Heike Hofstetter, the assistant director of the UW–Madison Chemistry Department NMR facility.
