Since the report of the discovery of sulfoximines by Whitehead and Bentley in 1952,[1] they have found numerous applications in organic synthesis.[2] For example, they have been used as building blocks in bioactive molecules [3] and pseudopeptides,[4] chiral auxiliaries for asymmetric synthesis,[5] and ligands for enantioselective metal catalysis.[6] In the latter context we and others have prepared sulfoximines, such as 1 and 2, which lead to ...
