title: Gold(I)-catalyzed intramolecular cycloisomerization of propargylic esters with furan rings.
abstract: A gold-catalyzed intramolecular cycloisomerization of α-yne-furans 1 is described in this contribution. A variety of cyclic α,β-unsaturated aldehyde or ketone derivatives and nitrogen-containing tricyclic adducts were obtained selectively in moderate to excellent yields under mild conditions by varying the substituents on the standard substrates.
