Abstract Palladiumbis(dibenzylideneacetone)/tri(2-furyl)phosphine-catalyzed cyclizations of dienyl acetates 2 in the presence of an (1-alkenyl)(tributyl)stannane and ZnCl2 provided trans-substituted 3-alkenyl-4-vinylcyclopentanes 11 in good yields. Analogous intramolecular carbometallation/C,C-coupling of enynyl acetates 4, 6, and 8 furnished, stereospecifically, monocylic trienes 19, 20, and 21, respectively.
