γ-Amino-β-ketosulfones as Chiral Educts: A Facile Synthesis of Enantiopure α-Amino Ketones.

-A new method for the preparation of enantiopure α-amino ketones, precursors of synthetically and pharmaceutically important β-amino alcohols, is developed via mono-or dialkylation of γ-amino-β-ketosulfones and subsequent reductive removal of the sulfonyl group. This strategy is extended towards γ-hydroxy-β-ketosulfones. The starting sulfones are prepared from chiral-pool materials according to reported protocols.
