Synthesis of 5-(hydroxy-, chloro-, bromomethyl)furan-2-enones Based on Fructose and their Antioxidant Activity

New enones were synthesized from 5-hydroxymethylfurfurol (5-HMF) and its derivatives using Wittig reactions of various phosphoranes. The synthesized enones were observed to affect free-radical oxidation in model systems, in particular, to suppress generation of reactive oxygen species.
