A new palladium-catalyzed carbocyclization of substrates containing two 1,3-diene moieties leads to the efficient, stereoselective preparation of functionalized cyclopentanes and pyrrolidines. Treatment of tetraenes with 5 mol % of a palladium catalyst and 2-10 equiv of an H-X trapping reagent effects carbocyclization under mild reaction conditions (25-65{degree}C) in good-to-excellent yields (50-94%) and with good to excellent stereoselectivity (5 to >20:1,trans;cis).
