(E)‐3‐(benzo[d][1,3]dioxol‐5‐ylmethylene)‐4‐(propan‐2‐ylidene)‐dihydrofuran‐2,5‐dione, we found a novel rearrangement and obtained the unexpected compound that is assigned as benzo‐medium‐ring anhydride instead of the expected compound. We described the novel rearrangement and a potential method for the synthesis of benzo‐medium‐ring anhydride derivatives.
摘要 当我们尝试合成 (E)-3-(benzo[d][1,3]dioxol-5-ylmethylene)-4-(propan-2-ylidene)-dihydrofuran-2,5-dione 时,我们发现新的重排并获得了意想不到的化合物,该化合物被指定为苯并中
环酸酐而不是预期的化合物。我们描述了新的重排和合成苯并中
环酸酐衍
生物的潜在方法。
