of α-substituted β-ketoesters promoted by C 2-symmetric iodoarenes as chiral agents and MCPBA as the oxidant is described. By a careful screening of the reaction conditions, promising enantiomeric excesses and moderate-to-good yields were obtained for the synthesis of β-ketoesters containing a stereogenic center. The catalytic asymmetric oxidation of α-substituted β-ketoesters promoted by C 2-symmetric
