TERT-BUTYL PROPIOLATE Chemical Properties,Uses,Production

Uses

tert-Butyl propiolate may be used in the preparation of heterocycles, alkaloids, and unsaturated amino acids.

Uses

TERT-BUTYL PROPIOLATE is used to prepare heterocycles,1,2 alkaloids,3 and unsaturated amino acids.4

General Description

tert-Butyl propiolate is an ester. It reacts with methimazole to afford tert-butyl (E)-3-(1-methyl-1H-imidazol-2-ylthio) acrylate. Crystallographic data for the lithium enolate of tert-butyl propiolate has been described..

Synthesis

TERT-BUTYL PROPIOLATE

13831-03-3

General procedure for the synthesis of tert-butyl propargylate from propargyl acid and tert-butanol: About 60 g of propargyl acid, about 100 g of N,N'-dicyclohexylcarbodiimide, about 10 g of 4-(dimethylamino)pyridine, and about 20 g of tert-butanol were dissolved in tetrahydrofuran, and the reaction was stirred for about 24 hours. Upon completion of the reaction, extraction was carried out with dichloromethane and water. The extracted organic layer was dried with a chemical desiccant and subsequently purified by column chromatography to give about 80 g of tert-butyl propargylate.
