White needle crystals. Melting point 141℃. | [Uses]
4-Oxo-4,5,6,7-tetrahydrobenzo[b]furan-3-carboxylic acid can be used as an intermediate of Propala. | [Definition]
ChEBI: 4-oxo-4,5,6,7-tetrahydrobenzo[b]furan-3-carboxylic acid is a member of benzofurans. | [Synthesis]
The methanol solution of resorcinol and potassium hydroxide is used to react with hydrogen under the action of active nickel to generate potassium 3-ketocyclohex-1-enolate, which is then cyclized with ethyl bromopyruvate under alkaline conditions , and then acidified to obtain ?4-oxo-4,5,6,7-tetrahydrobenzo[b]furan-3-carboxylic acid. |
