The formation of α,β-unsaturated carbonyl compounds by a catalytic alkyne-carbonyl metathesis, which can be catalyzed by both π- and σ-acids, has received attention as an atom economical process alternative to the Wittig reaction. During the last decade, the catalytic alkyne-carbonyl metathesis has provided attractive methods for the construction of various cyclic compounds. This review summarizes synthetic methods of heterocycles with a focus on recent advances in the catalytic alkyne-carbonyl metathesis of the unactivated alkynes.
