Abstract

Treatment of cyclic βKeto esters with terminal alkynes in the presence of a catalytic amount of a rhenium complex, [ReBr(CO)3(thf)] 2, gave bicyclo[3.3.1]nonene derivatives. The reaction conditions and yields of the bicyclo[3.3.1]nonenes were improved by the sequential use of tetrabutylammonium fluoride (TBAF) after the rhenium-catalyzed reactions.
