建立了一种以Pd(OAc)2、钼钒磷酸和路易斯酸在常压氧气条件下以丙烯酸酯和醛为原料合成取代糠酸酯的新方法。发现该反应通过钯催化的丙烯酸酯与甲醇的缩醛化反应进行，随后所得缩醛与醛反应。
A new synthetic method of substituted furoates from acrylates and aldehydes was developed by Pd(OAc)2 combined with molybdovanadophosphoric acid and Lewis acid under atmospheric dioxygen. The reaction was found to proceed through the palladium-catalyzed acetalization of acrylates with methanol followed by the reaction of the resulting acetals with aldehydes.
