The reaction converts saturated heterocycles with 6 atoms, including cyclic amines, ethers (example shown), and thioethers, into 5-carbon rings with pendant amines, alcohols, or thiols, respectively.

Chemists at the University of Oklahoma have now unveiled a new strategy for expanding 5-membered aromatic rings that already contain a nitrogen, by slipping in an extra nitrogen atom as the ring ...
