Under the reaction conditions of Pd(PPh) (2.5 mol %) and PPh (10 mol %) in EtOAc at 60 °C, the formal (5 + 6) cycloaddition of vinylethylene carbonates with isatoic anhydrides proceeded smoothly and furnished medium-sized ,-containing heterocycles in reasonable chemical yields. The chemical structures of the title products were clearly identified by X-ray diffraction analysis.
在 Pd(PPh) (2.5 mol %) 和 PPh (10 mol %) 的反应条件下，于 60°C 的 EtOAc 中，乙烯基碳酸乙烯酯与异吲哚-1,3-二酮的形式 (5 + 6) 环加成反应顺利进行，以合理的化学收率得到了中等大小的含杂环化合物。标题产物的化学结构通过 X 射线衍射分析得到了明确的鉴定。
