Title: reductones Long Title: IUPAC Gold Book - reductones DOI: 10.1351/goldbook.R05224 Status: current Definition Compounds containing an enediol structure stabilized by conjugation and hydrogen bonding with an adjacent carbonyl group, $\ce{RC(OH)=C(OH)C(=O)R}$. They are strong reducing agents, fairly strong acids and commonly derived from saccharides by oxidation at the carbon atom alpha to the carbonyl function, e.g. ascorbic acid.
