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.
