2-Acetylfuran is a low melting solid or high boiling liquid, depending on temperature.[1][2] The solid melts at 30 °C and has a density of 1.0975 g/ml at 20 °C, while the normal boiling point of the liquid is 168–169 °C.[3] 2-Acetylfuran is a useful intermediate in the synthesis of fine chemicals and pharmaceuticals, and is used in the production of the generic cephalophosphorin antibiotic cefuroxime.[4]


2-Acetylfuran was prepared by Ashina in 1914 via the reaction of the methyl Grignard reagent on 2-furonitrile.[5] Modern industrial synthesis generally involves the Friedel–Crafts acylation of furan with acetic anhydride.



A one-pot synthesis of an intermediate to the HIV integrase inhibitor S-1360 was based on the Friedel-Crafts alkylation of 2-acetylfuran with 4-fluorobenzyl chloride using zinc chloride catalyst.[6]

Reaction of 2-acetylfuran with aqueous sodium nitrite gave 2-furanyloxoacetic acid, an intermediate to Cefuroxime, a second-generation cephalosporin antibiotic.[7]
