introduction | tert-butyl propionyl ester is an organic intermediate used to prepare heterocyclic, alkaloid and unsaturated amino acids. tert-butyl propionic acid ester can be obtained by condensation of propionic acid and tert-butyl alcohol. |
Preparation | After dissolving about 60g of compound 17 (propionic acid), about 100gN,N'-dicyclohexylcarbodiimide, about 10 g4-(dimethylamino) pyridine and about 20g of tert-butanol in tetrahydrofuran, the mixture is stirred for about 24h. Then, the product of the reaction was extracted with dichloromethane and water, and about 80g of tert-butyl propionyl ester was obtained by chemical drying of the extracted organic layer and purification by column chromatography. |
use | used to prepare heterocyclic, alkaloid and unsaturated amino acids. |
