Organocopper compounds, prepared from Grignard reagents and copper(I) iodide in tetrahydrofuran-dimethyl sulphide, react with 2,3-O-isopropylideneglyceraldehyde highly stereoselectively (>10:1) affording the rarely obtained syn-addition products which can be readily converted into optically active epoxy alcohols, useful intermediates in organic synthesis.
由格氏试剂和碘化亚铜(I)在四氢呋喃-二甲基硫醚中制备的有机铜化合物与2,3- O-异亚丙基甘油醛高度立体选择性(> 10:1)反应,提供了很少获得的合成加成产物,可以轻松地将其转化为旋光性环氧醇,在有机合成中有用的中间体。
