application of a Paal–Knorr synthesis. In this manuscript, we investigate the chemoselectivity and diastereoselectivity of furansynthesisfrom 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–Benaryfuransynthesisfrom α-halo ketones and β-dicarbonyl compounds without any base or solvent
