aldehydes undergo an efficient E-stereoselective Horner-Wadsworth-Emmons olefination by generation of phosphonate carbanion with lithium hydroxide. The reaction proceeds satisfactorily with linear, cyclic, polifunctional ketones in the presence of activated zeolites and and by the slow addition of the base.
醛通过与氢氧化锂生成膦酸酯碳负离子而进行有效的E-立体选择性Horner-Wadsworth-Emmons烯化反应。在活化沸石的存在下,并通过缓慢添加碱,该反应可令人满意地用线性,环状,多官能酮进行。
