Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Methanol | HCID 887 | — |
| Reactant | 1,4-Anhydro-3,5-dideoxy-3-(ethoxycarbonyl)-1-methylpent-2-ulose | HCID 22768534 | — |
| Solvent | Benzyl Alcohol | HCID 244 | — |
| Product | HCID 22768536 | HCID 22768536 | 168.7% |
Reaction Steps
40 g of 4-oxo-2,5-dimethyl-3-carboethoxytetrahydrofuran in 200 ml of benzyl alcohol are heated at 180°-200° C. The methanol formed is distilled off. The excess benzyl alcohol is distilled off under reduced pressure and the residue is fractionated. 45 g (corresponding to 78% of theory) of 4-oxo-2,5-dimethyl-3-carbobenzyloxytetrahydrofuran of boiling point 102° C/0.02 mm Hg and refractive index nD25 = 1.5070 are obtained.
