| Ethyl propiolate Usage And Synthesis |
| 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 | In organic synthesis; peptide coupling reagent. | | 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. | | 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. |
