通过1,4 -二硅基- 2 -芳氧基- 1,3 -烯的分子内氢化反应，再与芳烃或烯烃进行环加成，最后进行去硅烷化反应，可快速合成各种苯并萘呋喃。三步转化可以在一个罐中依次操作，方便、高效地提供一系列呋喃二烯。
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.
