EPFL chemists have developed a new catalytic method for symmetry breaking. Published in Angewandte Chemie, the method can help synthesize important building blocks for bioactive compounds such as anticancer drugs.Many chemical molecules can exist in nature together with their mirror counterparts; like hands, two compounds can be made up of the same atoms in the same overall structure but in opposite orientations, i.e. left-handed and right-handed. This phenomenon of symmetry is called "chirality", and can give mirror counterparts ("enantiomer
