Enolates were generated from α,β-epoxy sulfoxides using lithium dimethylcuprate as an electron-transfer reagent. The enolates were trapped with several electrophiles, in which aldehydes reacted with the generated enolates giving aldols in good yields with high regioselectivity.
使用二甲基铜酸锂作为电子转移试剂从 α,β-环氧亚砜生成烯醇化物。烯醇化物被几种亲电子试剂捕获,其中醛与生成的烯醇化物反应,以高产率和高区域选择性得到羟醛。
