Synthesis of 3-acylfurans from 1,3-dicarbonyl compounds and aliphatic nitro-olefins
Abstract
Some 1,3-dicarbonyl compounds (acetylacetone, cyclohexane-1,3-dione, 5,5-dimethylcyclohexane-1,3-dione, and ethyl acetoacetate) and aliphatic nitro-olefins (2-nitropropene, 2-nitrobut-1-ene, and 2-nitrobut-2-ene) directly gave 3-acylfurans (8)–(15) in a KF-catalysed reaction.
