Synthesis of Cyclic Derivatives of Carbonyl Compounds of Furan Series

Cyclic acetals of furan aldehydes (furfural, 5-hydroxymethylfuran-2-carbaldehyde and furan-2,5-dicarbaldehyde) and alcohols (ethylene glycol and 2-sulfanylethanol) were synthesized. The effect of the ratio of the starting reagents on the yield of acetals obtained was studied.
