We show that native sugars can be directly merged with N-heteroarenes via redox-active thioglycosyl radical precursors using photocatalysis. Great collaboration with the Chan group from NUS Pharmacy to study the bioactivity of these compounds. #glycotime www.nature.com/articles/s44...

Electrifying skeletal editing? Our latest work on a tunable electrochemical method that enables divergent N-heterocycle synthesis via N insertion into carbocycles. #skeletalediting #expansion #electrochemistry #heterocycle

Another week, another atom swap! This one features adorable--and adorably versatile--oxetanes! cen.acs.org/synthesis/At...

A new photocatalytic atom-swapping method enables efficient conversion of oxetanes into diverse four-membered saturated rings, streamlining access to key pharmaceutical building blocks. doi.org/g96442

Swapping oxygen in oxetanes? 🪄 Done! With skeletal editing 🙌🏼🦴✨ My latest @chemistryworld.com story covers a cool strategy to introduce nitrogen, carbon, or sulfur instead at a single stroke 🖌️🎨 Amazing, almost magic @nature.com paper by @mjkoh87.bsky.social 👉🏼 www.chemistryworld.com/news/stimula...

Atom-swapping in a saturated heterocycle? We report a photocatalytic transmutation strategy in @nature.com that exchanges O within an oxetane for N, S, C & even dual atoms, affording various non-aromatic cyclic pharmacophores. #skeletalediting #atomswap #photocatalysis www.nature.com/articles/s41...

Excited to see our recent difluorocarbene skeletal expansion chemistry being used to make a molecule of the week! Read more about making difluorooxetanes from here: lnkd.in/gad_5fNq Now available from Enamine: new.enaminestore.com/catalog/EN30...

A new skeletal expansion approach to make γ-lactam pharmacophores by Cu-catalyzed difluorocarbene insertion into azetidines. It turns out that some γ-lactam scaffolds are harder to access than azetidines. Just accepted in @angewandtechemie.bsky.social. onlinelibrary.wiley.com/doi/10.1002/...

Our latest work in @naturechemistry.bsky.social using copper catalysis to promote difluorocarbene insertion into epoxides, allowing us to access an interesting but elusive class of α,α-difluoro-oxetane pharmacophores. www.nature.com/articles/s41...
