Mixed benzofuranyl carbonates derived from chiral chloroformates rearranged in the presence of nucleophilic catalysts to giveC-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,8kwas obtained with 9:1 dr.
