Evidence is presented which supports the intermediacy of dipolar Baylis-Hillman-type adducts in the synthesis of coumarin and chromene derivatives from the reaction of 2-hydroxybenzaldehydes with methyl acrylate in the presence of 1,4-diazabicyclo[2.2.2]octane (DABCO).
有证据表明，在1,4-二氮杂双环[2.2.2]辛烷（DABCO）存在下，2-羟基苯甲醛与丙烯酸甲酯反应合成香豆素和色烯衍生物的过程中，偶极贝利斯-希尔曼型加合物起到了中间体的作用。
