AbstractWe illustrate the first use of bulky N,N′-disubstituted cyclic thioureas as ligands for gold(I) catalysis. X-ray crystal structures of the thiourea-gold(I) complexes presented important information about the nature of the complexation. These complexes were found to be active catalysts for the cyclization of 1,3-dicarbonyl compounds with alkynes (Conia-ene reaction). Various acetylenic 1,3-dicarbonyl compounds underwent cycloisomerization to give mono- and bicyclic olefinic cyclopentanes in the presence of one mol% of a thiourea-gold(I) chloride complex and silver triflate. © Georg Thieme Verlag Stuttgart.
