Professor Benjamin List

The List group focuses on the development of new concepts in catalysis. Since 1999, this research group has pioneered the development of organocatalysis as the third pillar of stereoselective catalysis, along side biocatalysis and transition metal catalysis. Among others, proline and TRIP have been used as very effective catalysts in this area. In 2005, List et al. were first to introduce the concept of asymmetric counteranion-directed catalysis (ACDC). In this context, the List group has developed disulfonimide catalysts (“DSI-CataLists”), which can be employed as Brønsted-acid catalysts as well as counteranions in asymmetric organo-Lewis acid catalysis.

Angew Chem Int Ed Engl. 2009;48(24):4363-6. doi: 10.1002/anie.200901768.
Room to swing a cat: A chiral disulfonimide has been designed as a powerful new motif for asymmetric catalysis. As a first illustration, a highly efficient and enantioselective Mukaiyama aldol reaction has been developed (see scheme). The actual catalyst is proposed to be an N-silyl imide which is generated in situ....Read More

It takes three to make things go right: The first direct asymmetric three-component reaction of aldehydes, carbamates, and allyltrimethylsilane leading to enantioenriched homoallylic amines has been developed using a new chiral disulfonimide catalyst. The method employs readily available, inexpensive, and nontoxic starting materials and is applicable to both aromatic and aliphatic aldehydes.....Read More
