Intermolecular Au-catalyzed annulation of 1, 3-enynes and propargyl esters to selectively produce styrenes or fluorenes was developed. The product distribution may be controlled through selection of the catalyst counterion.Analytical GC was carried out with a Hewlett Packard HP 6850 GC equipped with an Agilent DB-WAX (30.0 m x 0.25 mm) column for achiral separation and a Chiraldex G-TA (30.0 m x 0.25 mm) column for chiral separation. The products wereanbsp;...
