Application

Gold Catalysts — 21st Century ′Gold Rush′
Catalyst employed in the cyclization of O-propargyl carbamates to alkylideneoxazolidinones via a 5-exo-digonal pathway at room temperature. Also catalyzes the cycloisomerization of enynes containing a cyclic olefin into highly-fused, polycyclic dienes at room temperature.
Reagent is used with cocatalytic halide abstraction agent to activate π-systems toward addition by heteroatom and carbon nucleophiles.

An efficient method for the synthesis of β-enaminones and β-enaminoesters using a combination of [(PPh(3))AuCl]/AgOTf as catalyst has been developed. The reaction between 1,3-dicarbonyl compounds and primary amines was carried out under solvent-free conditions with low catalyst loading in good

Gold(I)-catalyzed cyclization of enynes containing an olefinic cycle has been studied. The introduction of an olefinic ring instead of a terminal alkene in enynes dramatically increased the yield of the reaction. Enynes having an olefinic cycle were prepared by a
