Chemical Properties
White Solid
Uses
L-Gulono-1,4-lactone is a precursor in the biosynthesis of ascorbic acid, one of the many forms of Vitamin C.
Definition
ChEBI: L-gulono-1,4-lactone is the furanose form of gulonolactone having L-configuration. It has a role as a human metabolite and a mouse metabolite. It is functionally related to a L-gulonic acid.
Synthesis
50-81-7
1128-23-0
The general procedure for the synthesis of L-gulosonic acid-γ-lactone from L-ascorbic acid was as follows: 10% Pd/C catalyst (8.3 g) was added to a solution of L-ascorbic acid (83.9 g, 0.477 mol) in water (600 mL). The reaction mixture was placed in a Parr hydrogenator and hydrogenated for 62 hours at 48 psi hydrogen pressure and 18°C. Upon completion of the reaction, the reaction mixture was filtered to remove the catalyst and the filtrate was concentrated under vacuum to afford L-gulosonic acid-γ-lactone (81.0 g, 96% yield) as an off-white solid. The resulting solid was dried in a vacuum oven at 50 °C for 18 h. The melting point was measured to be 182-184 °C.
