A new reaction cuts nitrogen atoms out of secondary amines with surgical precision. The transformation offers a route to strained structures, such as cyclobutanes (example shown), that can be ...

Researchers at the University of Oklahoma have developed a breakthrough method of adding a single nitrogen atom to molecules, unlocking new possibilities in drug research and development. Now ...

An unconventional route for modifying pharmaceutically relevant molecules swaps an atom of carbon for one of nitrogen. The resulting derivatives might open up avenues of research in ...

As a graduate student at the University of California, Berkeley, Mark Levin started sketching out ideas for how to do something no chemist had ever managed before: swapping one of the carbon atoms in ...
