An efficient Et3N-catalyzed alkenylation of γ-substituted deconjugated butenolides with cyclic N-sulfonylated imines in water is described. The reaction proceeds efficiently under mild reaction conditions to give α-arylidene butenolide derivatives in high yield (82–96%).

描述了在水中有效的Et 3 N催化的γ-取代的去共轭丁烯化物与环状N-磺酰基亚胺的烯基化反应。在温和的反应条件下，反应可以高效进行，从而以高收率（82-96％）得到α-亚芳基丁烯内酯衍生物。
