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.

In this work we describe the cyclofunctionalization of eleven differently substituted alkenyl-β-dicarbonyl compounds, employing three electrophilic reagents, namely, iodine, ρ-methoxyphenyl-tellurium trichloride, and phenylselenenyl bromide. The reactions occur through the enolic form of the substrates, to afford the corresponding iodo-, telluro-, or selenocyclic enol ethers. Substrates bearing trisubstituted double bonds failed in reacting with the selenium and tellurium reagents. In general, β-diketones reacted faster than β-keto esters with the three studied electrophiles.
