一种制备异丙烯酮化合物的方法
摘要：
本发明公开了一种制备异丙烯酮化合物的方法，包括1)将式IV化合物与乙基膦酸酯溶于有机溶剂中，加入乙基膦酸酯活化剂，反应完全后，用淬灭剂终止反应，制得化合物V；2)将式V化合物与甲醛在溶剂中，在碱的存在下发生缩合反应，制得异丙烯酮化合物。该方法简便、高效、成本低廉，适用于工业化生产。
摘要（英）：

The invention discloses a method for preparing an isoptopenyl ketone compound. The method comprises the following steps: 1, dissolving a compound of formula IV and ethyl phosphate in an organic solvent, adding an ethyl phosphate activator, completing a reaction, and terminating the reaction by using a quenching agent to prepare a compound V; and 2, carrying out a condensation reaction on the compound of formula V and formaldehyde in a solvent in the presence of an alkali in order to prepare the isoptopenyl ketone compound. The method has the advantages of simplicity, high efficiency, low cost, and suitableness for industrial production.
