Preparation of dihydro-4,4-dimethylfuran-2,3-dione |
| abstract |
Dihydro-4,4-dimethylfuran-2,3-dione is prepared by oxidation of racemic dihydro-3-hydroxy-4,4-dimethyl-2(3H)-furanone by a process in which the oxidation is carried out by gradually adding powdered calcium oxide to a solution of racemic dihydro-3-hydroxy-4,4-dimethyl-2(3H)-furanone and chlorine in the inert organic solvent. |
