title: Palladium-Catalyzed Triple Cyclization of 2,7-Alkadiynylic Carbonates with Allenes Bearing a Carbon Nucleophile.
abstract: Palladium-catalyzed tandem reactions of 2,7-alkadiynylic carbonates with allenes bearing a carbon nucleophile such as malonate and bis(phenylsulfonyl)methane for the efficient syntheses of fused tricycles, such as 3,5,6,7-tetrahydro-1H-indeno[5,6-c]furan, 1,2,3,5,6,7-hexahydrocyclopenta[f]isoindole, and 1,2,3,5,6,7-hexahydro-s-indacene derivatives, have been reported. The reaction forms two five-membered rings and one benzene ring fusing them in the middle.
