A metal-free cyclization of olefinic dicarbonyl compounds for the synthesis of various 5-halomethyl-4,5-dihydrofurans is presented. Using (diacetoxyiodo)benzene as the reaction promoter and halotrimethylsilane as the halogen source, the intramolecular hal

Feist–Bénary furan synthesis, the reaction between α-halocarbonyl and β-dicarbonyl compounds, has been known as an efficient method for generating many different types of furans containing a carbonyl group at C-3. However, it has also been reported that, under similar reaction conditions, intermediate tricarbonyl species could be further converted to alternative furan isomers through the application of a Paal–Knorr synthesis. In this manuscript, we investigate the chemoselectivity and diastereoselectivity of furan synthesis from α-halo ketones and β-dicarbonyl compounds, by carrying out the separation and characterization of the intermediates involved in the reaction. Additionally, a one-pot Feist–Bénary furan synthesis from α-halo ketones and β-dicarbonyl compounds without any base or solvent has also been developed.
