Treatment of α-trimethylsilyl-α,β-unsaturated ketones with tetrabutylammonium fluoride in the presence of aldehydes provided α-(1-hydroxyalkyl)-α,β-unsaturated ketones in good yields. The reaction proceeded via allenolate. The new method was successfully applied to a synthesis of α-(1-hydroxyalkyl)-α,β-unsaturated esters from α-trimethylsilyl-α,β-unsaturated esters.
在醛的存在下用四丁基氟化铵处理 α-三甲基甲硅烷基-α,β-不饱和酮,以良好的收率提供了 α-(1-羟烷基)-α,β-不饱和酮。反应通过烯丙醇酯进行。新方法成功应用于由α-三甲基甲硅烷基-α,β-不饱和酯合成α-(1-羟烷基)-α,β-不饱和酯。
