Ethyl propionylacetate Chemical Properties, Uses, Production

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.
