Methyl tetrahydro-4H-pyran-4-one-3-carboxylate-4 - Reference Information
| Introduction | methyl 4-oxotetrahydro-2h-pyran-3-carboxylate due to the presence of conjugated double bonds and ester groups, tetrahydropyrone derivatives are important intermediates in organic synthesis. In organic synthesis, tetrahydropyrone can be used as a Diene body to react Diels-Alder with alkyne, ENE, etc. In particular, in recent years, asymmetric Diels-Alder reactions of tetrahydropyrone with various Dienes catalyzed by chiral organic bases and the synthesis of natural products using tetrahydropyrone as a precursor material, further enriched the tetrahydropyrone chemistry. |
| Use | methyl 4-oxotetrahydro-2h-pyran-3-carboxylate is a carboxylic acid ester derivative, it can be used as pharmaceutical and chemical intermediates. |
| synthesis method | take a clean three-mouth reaction bottle, start the stirring device, add tetrahydropyrone, dichloromethane solution, triethylamine was added to the methanol-dichloromethane solution of tetrahydropyrone, and a dichloromethane solution of dimethyl carbonate was added dropwise. After dropping, the system was heated to 50 ° C., and the cooling reflux device was started. Reaction 15 hours, thin layer chromatography to detect the progress of the reaction. At the end of the reaction, the oil bath was removed, the solvent was distilled off under reduced pressure, and the concentrate was chromatographed on a silica gel column [eluent: V (ethyl acetate)/V (petroleum ether)]. = 1/10] The compound 4-oxotetrahydro-2h-pyran-3-carboxylic acid methyl ester was purified. |
