Ein Schweizer Messer ist eine geniale Erfindung, das Universalwerkzeug lässt sich für viele Zwecke nutzen. Die Synthese-Chemiker Benjamin List und Ilija Čorić vom Max-Planck-Institut für Kohlenforschung haben ein chemisches Werkzeug entwickelt, das zwar viel kleiner, aber ähnlich vielseitig und gleichzeitig präzise ist: einen neuartigen enantioselektiv arbeitenden Katalysator. Solche Katalysatoren produzieren fast ausschließlich eine von zwei möglichen, chemisch sehr ähnlichen Formen einer Substanz und könnten damit die Herstellung vieler Pharmazeutika erleichtern.
Die beiden Chemiker Benjamin List und Ilija Čorić erforschen, mit welchen chemischen Werkzeugen man chirale Moleküle auf einfache Weise herstellen kann. Chiral heißen diese Moleküle, weil sie in zwei oswwzrmruonoj Vqfysx enctysofm, yiw ivpc mbh qeg lxree akl xov jvabje Iuxo powfzgbngmaujuq twirouusxl wegltggda.
