Copper(II) bromide-catalyzed conjugate addition of furans to α,β-unsaturated carbonyl compounds

[Figure not available: see fulltext.] A simple method for the synthesis of 2-(3-oxoalkyl)furan derivatives based on conjugate addition of 2-substituted furans to various α,β-unsaturated carbonyl compounds in the presence of copper(II) bromide as catalyst was developed. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.
