title: Gold-catalyzed tandem cycloisomerization-hydroalkoxylation of homopropargylic alcohols.
abstract: The tandem cycloisomerization-hydroalkoxylation of various homopropargylic alcohols in the presence of an alcohol and a dual catalyst system, consisting of a gold precatalyst and a Brønsted acid, provides an efficient route to tetrahydrofuranyl ethers under mild reaction conditions. The reaction can be carried out in various solvents, including alcohol, with both terminal and internal alkynes as the substrate.
