Facile synthesis of various benzonaphthofurans was achieved by intramolecular hydroarylation of 1,4‐disilyl‐2‐aryloxy‐1,3‐enynes followed by cycloaddition with arynes or alkenes and finally desilylaromatization. The three‐step transformation can be operated sequentially in one‐pot, providing with a range of furanoacenes easily and highly effectively.
各种苯并萘呋喃的简便合成是通过1,4-二甲硅烷基-2-芳氧基-1,3-烯炔的分子内加氢芳基化反应,然后与芳烃或烯烃环加成,最后进行脱甲硅烷基芳构化。三步转换可在一个锅中顺序进行,从而轻松高效地提供了一系列呋喃并酮。
