• potential for use in asymmetric catalysis. Results Asymmetric deprotonation of N-trialkylsilyl dimethyl sulfoximines with either enantiomer of lithium N,N-bis(1-phenylethyl)amide in the presence of lithium chloride affords enantioenriched sulfoximines on electrophilic trapping. Ketones, ketimines

• dimethyl sulfoximines is possible. Introduction The preparation of enantioenriched sulfoximines is an important goal in synthesis as these S-chiral compounds make interesting ligands for asymmetric catalysis and have been used in the construction of pseudopeptides.

• catalytic profiles without the need to prepare new ligands. The application of combinatorial chemical methods in asymmetric catalysis has emerged as a promising area of research, and indeed several reviews covering the subject have appeared.[1][2][3][4][5][6][7][8] It is based on the preparation of

• still to be discovered. Four years ago, the Nobel prize in chemistry celebrated chemists' achievements in asymmetric catalysis – and even since then the face of catalysis is changing, with for example metathesis and organocatalytic methods constantly breaking into new areas. Synthesis is changing too
