We report Au(I)- and Ag(I)-catalyzed cycloisomerizations of epoxide-alkyne functionalities in both aromatic and nonaromatic systems, leading to diversified carbocyclic and heterocyclic frameworks with high chemoselectivities. The use of such cycloisomerizations is reflected by a facile access to the cores of natural pallidol and gibberic acid.
