Fang, Yewen,Li, Chaozhong
, p. 3574 - 3576 (2005)
The first copper-catalyzed intramolecular O-vinylation of carbonyl compounds with vinyl bromides was reported, among which the efficient formation of 5-, 6- and even 7-membered cyclic alkenyl ethers was achieved with β-ketoesters as nucleophiles. The Royal Society of Chemistry 2005.
W(CO)5(L)-catalyzed cyclization of α-alkynyl-β- dicarbonyl derivatives: Synthesis of methylenelactones, furans, and methylenecyclopentanes

W(CO)5(L)-Catalyzed cyclization of α-alkynyl-β-keto acids, keto esters, and diketones provides methylenelactones, furans, and methylenecyclopentanes via 5-exo-dig cyclization. Also, the present approach can be further applied to 5-endo-dig cycl
A CONVENIENT APPROACH TO FURAN DERIVATIVES BY I2-INDUCED CYCLISATION OF 2-ALKENYL SUBSTITUTED 1,3-DICARBONYL COMPOUNDS
Antonioletti, R.,Bonadies, F.,Scettri, A.
, p. 4987 - 4990 (2007/10/02)
5-iodoalkyl-4,5-dihydrofurans 2, 5-alkylidene-4,5-dihydrofurans 3 and 2,3,5-trisubstituted furans 4 are obtained through a simple sequence, involving, in the key-step, a regio- and stereoselective iodoenoletherification of 2-alkenyl substituted 1,3-dicarbonyl compounds 1.
