Tandem Reactions of Ynones: via Conjugate Addition of Nitrogen-, Carbon-, Oxygen-, Boron-, Silicon-, Phosphorus-, and Sulfur-Containing Nucleophiles

Ynones are widely used in organic synthesis. Their great success is rooted in their multiple functional groups. This review focus on advance of ynones in published in the decade 2009-2019. Reactions triggered by the conjugate addition of nitrogen-, carbon-, oxygen-, boron-, silicon-, phosphorus-, and sulfur-containing nucleophiles are thoroughly discussed and summarized herein. Multicomponent reactions, rearrangements, cycloadditions, regio- and stereoselective synthesis, oxidations, coupling, green chemistry et al. are depicted in detail. We hope that this review will promote future research in this area.
