Ethyl propiolate Chemical Properties,Usage,Production
Chemical Properties
Ethyl propiolate is a clear colorless to pale yellow liquid that is soluble in ethanol, ether and chloroform. It an important organic chemical raw material and pharmaceutical intermediate. Ethyl propargylate is obtained by oxidation of propargyl alcohol to propargylic acid followed by esterification.
Uses
Halogenated derivatives were used as substrates for direct, asymmetric alkynylation of cyclic ?-ketoesters using chiral phase-transfer catalysts. Also employed in a one-pot , four-component synthesis of benzene-1,2,3,5-tetracarboxylates promoted by Ph3P.
Uses
Ethyl propiolate is used as a precursor in the preparation of substituted anthraquinones and pyrazolo[1,5-a]pyridine, which exhibits anti-inflammatory activity. Further, it is employed in the synthesis of benzene-1,2,3,5-tetracarboxylates promoted by triphenylphosphine. Its halogenated derivatives are used as a substrate for direct, asymmetric alkynylation of cyclic beta-ketoesters using chiral phase-transfer catalysts.
Uses
In organic synthesis; peptide coupling reagent.
Definition
ChEBI: Ethyl propiolate is the ethyl ester of prop-2-ynoic acid. It is a ynoate ester, a terminal acetylenic compound and an ethyl ester.
Hazard
Flammable; lachrymator.
