Copper-catalyzed remote yne-allylic substitution system is efficient approach for constructing functional molecules containing unsaturated bonds, and a variety of new catalytic systems and reaction modes have been successfully developed. Yne-allylic ester substrates with remote leaving groups are converted into copper vinyl-allenylidene intermediates under the cooperative catalysis of copper/ligands. The nucleophilic addition of nucleophiles to the γ-position or ε-position of the intermediates can efficiently construct important skeletons such as structurally diverse 1,3-enynes, 1,4-enynes, allenes, spirocyclic compounds, and C-C/C-N/N-N axially chiral compounds. From the perspective of classification by nucleophile types, this article systematically summarizes the latest research progress of copper-catalyzed remote yne-allylic substitution reactions involving various nucleophiles such as carbon, nitrogen, and sulfur. It focuses on the discussion of reaction mechanisms and prospects for the future development direction of this field.
