Formaldehyde → HCID 20373310, compound

Participants

Reaction Steps

A mixture of 10 g of 2,5-dimethyl-4-hydroxy-3-(2H)-furanone, 20 ml of a 37% formaldehyde aqueous solution, 50 ml of water and 0.7 g of oxalic acid was stirred for 18 hours at room temperature. After working up the reaction mixture, the crude reaction product was purified by column chromatography over polyamide. Elution with pentane-dichloromethane 80/20 yielded the pure 2-hydroxymethyl-2,5-dimethyl-4-hydroxy-3-(2H)-furanone, which was recrystallized from ethyllactate m.p. 124°-125° C.
