Breaking carbon-hydrogen (C-H) bonds to alter existing molecules to create new ones is an increasingly important avenue for drug development. Of particular interest is mirror-image or "one-handed" compounds, but C-H breaking ...

(Phys.org) —A new study by chemists in Switzerland is likely to change the way many stereoisomer molecules are synthesized for industrial, agricultural, or medical uses.
Many molecules have a right and a left form, just like shoes. In pharmaceuticals, it is important that the correct form of the molecule is used. Researchers at the University of Gothenburg, Sweden, have been able to produce ...
