摘要：

(Chemical Equation Presented) Synthesis of chiral sulfones: A copper-phosphine complex efficiently provided optically active alkyl phenyl sulfones by hydrosilylation at room temperature. The reduction of β,β-disubstituted vinyl sulfones in the presence of the Me-DuPhos monoxide ligand lead to excellent enantiomeric excesses and high yields (see scheme). The prepared chiral sulfones were desulfonylated and subjected to Julia olefination conditions. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
