| | Ethyl propionylacetate Usage And Synthesis |
| Chemical Properties | colourless liquid | | Uses | An intermediate of Rosuvastatin. | | Uses | Ethyl propionylacetate acts as a precursor used in the preparation of 1-ethyl- and 1-n-propyl-1,3,4,9-tetrahydropyrano[3,4-b]indole-1-acetic acid bearing one or two substituents on the benzene ring. Further, it is used to prepare 3-propionyl-2H-cyclohepta[b]furan-2-one. | | Uses | Ethyl propionylacetate has been used in the synthesis of 1-ethyl- and 1-n-propyl-1,3,4,9-tetrahydropyrano[3,4-b]indole-1-acetic acid bearing one or two substituents on the benzene ring. | | Synthesis Reference(s) | Synthesis, p. 829, 1978 DOI: 10.1055/s-1978-24903 | | General Description | Ethyl propionylacetate reacts with tropolone p-toluenesulfonate in the presence of sodium ethoxide to give 3-propionyl-2H-cyclohepta[b]furan-2-one. |
