Alkaline hydrolysis of 3,3,4,4-tetrahydroxy-5-phenyl-4,5-dihydrofuran-2(3H)-one (2) leads to complete fragmentation of the molecule with formation of oxalic acid, mandelic acid and benzoic acid.In neutral medium, besides evolution of CO2 and formation of an aci-reductone (3), a small amount of a yellow precipitate is formed, which is shown - in correcting previously published assumptions - to be a mixture of two compounds, namely a furan-2-carboxylic acid derivative (5) and its decarbonylation product, a furan-2-one (6), the basic compound of the "pulvinone"-series.The crystal and molecular structure of (5) has been determined. (5) crystallizes triclinically in space group P (2) with two molecules per unit cell.
