A copper-catalyzed electrophilic enamidation starting from alkynes is reported. Hydrozirconation of an alkyne with the Schwartz reagent forms a vinyl zirconium intermediate, which directly undergoes a copper-catalyzed electrophilic enamidation with dioxazolones. High functional group tolerance of hydrozirconation enables the use of functionalized alkynes including esters. The developed conditions are successfully applied to syntheses of partial structures found in biologically active natural products.
