An efficient synthesis of fused furans from 2-alkynylcycloalk-2-enols via gold(III) bromide catalyzed cycloisomerization was achieved. The reaction condition is moderate and amenable to structurally diverse substrates, leading to good yield of products.

of diverse furan derivatives from acetylenic alcohols by gold and palladium catalyzed π-activation chemistry. Notably, this new method was found to be amenable to cyclooctyl-containing substrates, which represents a significant extension to this methodology compared with our previous reports. Furthermore, this newly developed method allowed for the direct construction of cyclooctyl furans from their
