A convenient and environmentally-friendly synthetic method of olefins via deacylation reaction is described. The reaction gives olefins by condensation of aldehydes with a variety of 1,3-dicarbonyl compounds in the presence of anhydrous potassium carbonate at room temperature in high yields (70–90%) in one step. The synthetic potential of this strategy can be used as an alternative procedure to the
描述了一种通过脱酰基反应的方便且环境友好的烯烃合成方法。在无水碳酸钾存在下,室温下一步反应将醛与各种1,3-二羰基化合物缩合反应,可制得烯烃。该策略的综合潜力可作为Wittig,Wittig-Horner反应的替代方法。通过正确的射频和X射线分析的NOE实验确定了所得烯烃的立体化学。脱酰反应的E / Z选择性取决于1,3-二羰基化合物的α-取代基。
