- Abstract
An efficient and facile method for the Paal-Knorr furan synthesis using titanium tetrachloride as dehydrating agent is described. Tricarbonyl compounds, prepared through the nucleophilic substitution of α-halogenated ketones and β-dicarbonyl compounds, are easily condensed to their corresponding polysubstituted furans. The reaction also occurs efficiently with tetracarbonyl compounds derived by dimerization of β-dicarbonyl compounds.
