Samarium alkoxides of alpha-hydroxy-[3]-cumulenes, generated in situ by SmI2-promoted reduction of appropriate epoxypropargyl esters, are found to participate in novel Pd-catalyzed cyclization/allylation sequences in the presence of allylic bromides. This results in the efficient regioselective formation of polysubstituted furans incorporating the allyl unit. (C) 2003 Elsevier Science Ltd. All rights reserved.
