  Diastereoselective Carboxyl Migrations of 3-Arylbenzofuranones

  摘要：

  [GRAPHICS]Mixed benzofuranyl carbonates derived from chiral chloro-formates rearranged in the presence of nucleophilic catalysts to give C-carboxylated benzofurans with variable dr. The use of chiral nucleophilic catalysts gave modest improvement in dr, but better results were obtained by optimizing auxiliary and catalyst. Thus, 8k was obtained with 9:1 dr.
