Indium-mediated allylations of EEDQ with various allyl bromides in the presence of 1.2 equiv. of acetic acid at rt gave the corresponding allylated dihydroquinolines with high a selectivities in high yields. The allylations of EEDQ with limited allyltins and allylsilane in the presence of BF 3 •Et 2
Indium-mediated allylation reactions of a-ketoimides derived from Oppolzer's sultam were accomplished in aqueous THF in good yields and excellent diastereomeric excesses. It could be a useful method for the preparation of enantiopure t-a-hydroxy acids. When the substituent of a-ketoimides was change
