In chemicals used in agriculture, as well as in pharmaceuticals and a variety of materials, pyridines are often found as so-called functional units that decisively determine the chemical properties of ...

A two-step process inserts a carbon atom into the aromatic nitrogen-containing rings of pyrroles and indoles to expand them into pyridines and quinolines, respectively. The technique expands the tool ...

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 ...
