The tandem cyclization of olefinic carbonyls with easily accessible diselenides facilitated by electrochemical oxidation has been successfully developed, which provides an environmentally friendly method for the construction of C-Se and C-O bonds simultaneously. A series of seleno dihydrofurans and seleno oxazolines, bearing fragile heterocycles, subtle C-I bonds and supernumerary vinyl groups, were forged using this elegant chelation strategy. Neither metal catalysts nor external chemical oxidants are required to promote this transformation.
Alcohol substitution and dehydrogenation of selenium compounds: A convenient preparation of trisubstituted furans from allyl-substituted 1,3-dicarbonyls

Trisubstituted furans have been synthesised efficiently by an alcohol substitution and dehydrogenation reaction of selenocyclic enol ethers which were prepared by organoselenium-induced regioselective electrophilic intramolecular cyclisation of allyl-substituted 1,3-dicarbonyls.

A number of alkenyl-substituted α-phenylseleno β-ketoesters can be cyclised in the presence of acidic catalysts in which a novel migration of phenylseleno moiety occurs.
Selenium-mediated Cyclization Reactions of Alkenyl-substituted β-Ketoesters
Jackson, William P.,Ley, Steven V.,Whittle, Alan J.
, p. 1173 - 1174 (2007/10/02)
Phenylselenating agents, in which the counter ion is non-nucleophilic, react with certain alkenyl-substituted β-ketoesters to afford cyclized products, some of which can be further rearranged using SnCl4.
