Andreas Pfaltz has a longstanding interest in the design of chiral ligands for asymmetric catalysis. The semicorrins developed in his group served as the prototype for an important family of nitrogen ligands, the bisoxazolines, which have found widespread use in catalytic asymmetric synthesis.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
