| | Dimethyl malonate Usage And Synthesis |
| Description | Dimethyl malonate is a diester derivative of malonic acid. It is a common reagent for organic synthesis used, for example, as a precursor for barbituric acid. It is also used in the malonic ester synthesis. It can be synthesized from dimethoxymethane and carbon monoxide. | | Chemical Properties | liquid | | Chemical Properties | Dimethyl malonate is soluble in alcohol and ether and very
slightly soluble in water. It may slowly decompose. | | Uses | It is used in fragrances and some artificial flavorings . | | Uses | Dimethyl malonate is a reagent used in organic synthesis. It acts as a precursor for the synthesis of mono-substituted and di-substituted acetic acid, barbiturates, vitamin B1 and vitamin B6. It is used in the pharmaceutical industry to prepare pharmaceuticals like chloroquine and butazolidin. It is involved in the synthesis of diastereomeric pure thienylpyridines by reacting with 1,3-diphenylprop-2-enyl acetate. | | Application | Dimethyl malonate undergoes enantioselective palladium-catalyzed allylic substitution reaction with 1,3-diphenylprop-2-enyl acetate to yield diastereomeric pure thienylpyridines.
Dimethyl malonate was used in gold catalyzed oxidative esterification of glycerol, 1,2-propanediol and 1,3-propanediol. | | Production Methods | Dimethyl malonate is produced via direct esterification of
methanol with malonic acid under azeotropic conditions. | | General Description | Dimethyl malonate undergoes enantioselective palladium-catalyzed allylic substitution reaction with 1,3-diphenylprop-2-enyl acetate to yield diastereomeric pure thienylpyridines. |
