Highly regioselective reductions of α,β-unsaturated ketones to the corresponding allylic alcohols were performed in essentially quantitative yields in aqueous media containing either glycosidic surfactants or amphiphilic carbohydrates. Reductions of cyclohexanones and cyclohexenones lead under the same conditions, stereoselectively to reduced compounds bearing an equatorial alcohol function. Hydrophobic
在含有糖苷型表面活性剂或两亲性碳水化合物的水性介质中,以基本上定量的产率将α,β-不饱和酮高度区域选择性地还原为相应的烯丙基醇。环己酮和环己酮的还原反应在相同条件下进行,立体选择性地还原了具有赤道醇功能的化合物。两亲性碳水化合物和亲脂性底物之间的疏水相互作用被建模,并应考虑到观察到的立体分化。
